Most Writers Are Writers

""Bad books on writing and thoughtless English professors solemnly tell beginners to write what you know, which explains why so many mediocre novels are about English professors contemplating adultery.""

- Joe Haldeman

You don't say.

Seriously, though. In fiction, it is relatively common for the main character to be a writer or a reporter. This is in large part because many narrative works of art are initially driven by writers themselves (novelists, playwright, screenwriters, etc.)

Interestingly, such characters are only occasionally Author Avatars. As the page quote indicates, one of the main pieces of advice writers hear is "Write What You Know", and since, as writers, they know writing, they have some idea how a writer would react in a given situation. This trope is almost unavoidable when the setting revolves around a Show Within a Show, and may lead to a Writer's Block Montage. Making characters who are writers by trade has a number of advantages for a narrative.
 * It helps get past the whole Realistic Diction Is Unrealistic problem, since a writer would be expected to know how to use big fancy words.
 * Journalists and other kinds of nonfiction writers generally are expected to have investigative skills and an attention to detail that are useful to many kinds of plots, such as They Fight Crime.
 * Even if they don't use those skills in the plot, journalists are generally close to a wide variety of local important people like politicians and big events like disasters, but not actually one of those people or part of those events. This is the in-universe reason why Superman and Spider-Man went into journalism in the first place, so they could keep their ears to the ground and find out when and where superheroes are needed.
 * Freelance writers and journalists have a semi-plausible excuse for their One-Hour Work Week.
 * Fiction writers in-universe, because of that same "write what you know" principle, can theoretically have every Chekhov's Skill an amateur could plausibly have if they had researched it for a book.
 * However, writers who don't write also don't get paid, which means this can become One-Hour Work Week if the writer never actually gets around to doing any writing, or if they spend too much time doing something other than writing.

This can tie into the Literary Agent Hypothesis, particularly if the story is written in the first person, i.e. the writer protagonist had an adventure, wrote up his account of it, published it and this is supposedly the book you have just read.

As a corollary to this, there are a disproportionate number of movies about the movie industry, a disproportionate number of plays about actors and playwrights, a disproportionate number of songs about singers, and so on.

A consequence of this is that there is a disproportionate number of works involving the difficulties associated with getting a job after college when you have an English major, even if it's a good economy, as all the writers were English majors, and virtually none of them could find a job after college, even in a good economy.

Anime and Manga

 * Sumiregawa Nenene of Read or Die.
 * There's also a number of manga about making manga, or at least doujin: Genshiken, Comic Party, Doujin Work, Bakuman｡.
 * And then there's Even a Monkey Can Draw Manga...
 * Manga that contain characters that are writers are also plentiful: School Rumble, Naruto, Junjo Romantica, Kodocha, Otaku no Musume San and Fairy Tail.
 * In Ichigo Mashimaro, Miu tries her hand at being a writer of manga, but her works are a bit surreal for Chika.
 * Bakuman｡ is a manga about manga, with the main characters being a manga artist and author, and is coincidentally produced by a writer and an author as separate people.
 * Himeko's mother from Himechan no Ribon is a writer of young women's romance novels who often takes ideas from the real world into her stories, with little changes.
 * Galaxy Express 999 does this several times. At one point, a poor person Tetsuro meets is a would be anime creator (who we are told, did manage to get her anime created), and episode 58 features a ghost who was a would-be manga writer in life. Episodes 60-61 have another would be manga artist, and another one shows up in episode 101. And 111 too.
 * Sai Nanohana, father to Jubei-chan, popular writer of samurai period pulp, and Author Avatar.
 * Fairy Tail has Supporting Protagonist Lucy who has spent much of the series on writing a book. The trope is even played with when she tries to trick a villain by saying she needs to go the bathroom. The villain has prepared for such a cheap trick and shows Lucy a bucket that she may use instead of a toilet. Lucy pretends that she is actually going to use the bucket. The villain is embarrassed and looks the other way, and Lucy uses the opportunity to kick him in the crotch. She then notes that despite the bathroom trick being one of the oldest ones in the book, it actually worked, and that she might use it in her own novel.
 * Daily Lives of High School Boys have the "literature girl," who wrote a Romance Novel... and then trying to re-enact the scene herself.
 * Sae of Hidamari Sketch is a seventeen-year-old who's already writing commercially.

Comic Books

 * Clark Kent and Lois Lane from the Superman mythos are both reporters.
 * Supreme is a comic book artist.
 * Also in DC Comics, Sam Simeon (of Angel and the Ape), R. Rodney Rabbit (aka Captain Carrot), and Kyle Rayner (one of Earth's many Green Lanterns) are comic book artists.
 * Daniel Clowes (Eightball) frequently writes about artists and writers. Enid Coleslaw of Ghost World was an artist, as is Dan Pussey of Pussey! It's alluded to in David Boring that the title character is a multimedia artist. At least two of the main characters (including the main character) of Ice Haven are writers. Twentieth Century Eightball is a collection of short-stories from Clowes, many of which are about artists (Art School Confidential, Ink Studs, etc.).
 * Spider Jerusalem.
 * Steve Rogers has worked as a comic book artist - even illustrating a Captain America comic!
 * Tintin is nominally a reporter, although he has only rarely been seen to file any stories.

Film

 * The main character from 2012 was a novelist, albeit an unsuccessful one.
 * Throw Mama From The Train.
 * In Moulin Rouge, Christian is a struggling writer.
 * Barton Fink is about a writer suffering from writer's block, written while the Coens themselves were having difficulty with Miller's Crossing. This writer really wants to make arty, weighty, important movies about the plight of the common man, similar to his successful play, but gets assigned a wrestling picture instead.
 * In the film Croupier the protagonist (played by Clive Owen, no less) is a novelist working as a croupier for a day job. The film really starts to get interesting when he commences writing a thinly disguised roman á clef entitled "I, Croupier", the plot of which resembles his own life.
 * Charlie Kaufman's Adaptation is a particularly surreal take on this trope. Kaufman himself (as played by Nic Cage) is the protagonist, and the movie is at least in part about the writing of itself.
 * It gets even more surreal. The writer credits for the movie include Donald Kaufman, Charlie Kaufman's fictional twin brother, who's also a character in the movie, and also a writer.
 * Stranger Than Fiction also uses the device in an eerie, roundabout and darkly humorous manner.
 * Sunset Boulevard: Protagonist and narrator Joe Gillis is a screenwriter, and this proves important - he catches Norma Desmond's interest as she believes he can help her complete the script of her great comeback film. To complete the triangle, Joe's girlfriend Betty is another aspiring screenwriter.
 * Shakespeare in Love, naturally.
 * Marty's father becomes a bestselling science fiction author in Back to The Future.
 * Gordie, the protagonist of Stand by Me, writes and tells stories as a teenager; the movie ends by showing us the now-adult Gordie writing the events of the film on his computer, while his son irritably waits to be taken to the pool.
 * Brother Gilbert in Dragonheart wants to compose epic ballads, and spends part of the film trying to write one about protagonist Bowen.
 * Confessions of a Shopaholic toys around with it a bit.
 * It would be shorter to list the Woody Allen movies where one of the main characters isn't a writer.
 * A character in Lady in the Water is a pretty blatant Author Avatar Mary Sue: a writer whose future work is destined to save the world. Did I mention that M. Night Shyamalan played the character himself?
 * A Knight's Tale had Geoffrey Chaucer as a character.
 * Romancing the Stone is about a female author who gets pulled into a treasure hunt alongside a rugged male adventurer played by Michael Douglas. It was written by a female writer who got pulled into the world of Hollywood by Michael Douglas.
 * In Withnail and I, the character only officially known as "I" is a writer, but all he writes is "just thoughts, really." His writing serves as the movie's occasionally Fauxlosophic Narration.
 * On a more meta level: it has been pointed out that most depictions of office work in film center on getting ready for some "big presentation." Office work doesn't rely much on presentations, really -- but film writers live or die by how well they present their story ideas.

Literature
""But I like Arthur," said Phyllis, and she smiled--the first time Garnet had seen her do so.
 * Morag Gunn, the protagonist of Margaret Laurence's novel The Diviners, is a writer.
 * The Hitchhiker's Guide to the Galaxy: Ford Prefect's job as a writer for the eponymous Encyclopedia Exposita provides him with an excuse to go on his dangerously irresponsible adventures. His problems with his editors, who butchered a long, complex, beautifully-written article he spent fifteen years on into one word, are a major point in the series.
 * And Arthur Dent worked for the BBC. Take a guess at who Douglas worked for. This gets lampshaded in the Quandary Phase of the radio series, where Arthur's producer is played by the original producer of Hitchhiker's, Geoffrey Perkins.
 * Richard Matheson's short story Mad House focuses on a writer with a nasty case of writer's block, among other problems.
 * And the protagonist in What Dreams May Come was a writer for television. He was made a pediatrician in the movie.
 * The protagonist of Larry Niven's Inferno, Allen Carpentier, is a Speculative Fiction writer, just like Niven. In some ways Carpentier seems to represent Niven, and expys of many other SF authors and other then famous personages appear in the story, but at the same time Carpentier's depiction is used to savage personal shortcomings that Niven himself might reasonably have.
 * Jo March (later Bhaer) of Little Women
 * Jo is pretty much a perfect example of an Author Avatar (although in general, done quite well), so this makes perfect sense.
 * Robert A. Heinlein loves this trope. Among his protagonists who are writers who bear more than a passing resemblance to the author or friends of his:
 * Jubal Harshaw of Stranger in A Strange Land, who writes in a variety of genres and media, under a bunch of pseudonyms.
 * Hazel Stone of The Rolling Stones, who writes a pulpy sci-fi adventure TV series.
 * The nameless protagonist of All You Zombies-- , who spends some time writing stories for a "True Confessions" magazine, and gets the nickname "The Unmarried Mother" partly from this fact.
 * The protagonist of The Cat Who Walks Through Walls is a fiction writer who lives on a orbital space colony.
 * The final chapter of The Number of the Beast is a huge cross-dimensional convention attended by sci-fi authors and characters from multiple fictional universes.
 * Footfall by Larry Niven and Jerry Pournelle features several sci-fi authors, including clear Author Avatar versions of both authors as well as one of Robert A. Heinlein, brought together by the government to help think up ways to fight an alien invasion.
 * Lucifer's Hammer by the same authors (and partly based on a scene from the first draft of Footfall that their editor demanded they expand into a novel in its own right) features writers and journalists among the Loads and Loads of Characters living through the collapse of civilization after a major comet impact.
 * Quite a few of Stephen King's protagonists are also writers.
 * Novelists:
 * Misery: Paul Sheldon
 * 'Salem's Lot: Ben Mears
 * The Dark Tower: He's written himself into the story (though not as the protagonist).
 * Word Processor of the Gods a short story in the collection Skeleton Crew
 * The Ballad of the Flexible Bullet, also in Skeleton Crew: Reg Thorpe
 * The Tommyknockers: Roberta "Bobbi" Anderson
 * The Dark Half: Thad Beaumont
 * IT: Bill Denbrough, a horror writer.
 * The Langoliers, a novella published in the collection Four Past Midnight: Bob Jenkins
 * Secret Window, Secret Garden, also in Four Past Midnight: Mort Rainey
 * Desperation, and The Regulators: Johnny Marinville
 * Bag Of Bones: Mike Nonan is a novelist suffering from writer's block.
 * Lisey's Story: Scott Landon (Lisey's deceased husband)
 * The Body (AKA Stand by Me) Gordon Lachance
 * Umney's Last Case, a short story in Nightmares and Dreamscapes
 * The Road Virus Heads North, a short story in Everything's Eventual: Richard Kinell, a horror writer.
 * Big Driver, a short story in Literature/Full Dark No Stars: Tess, a mystery writer.
 * Non-novelist writers:
 * The Colorado Kid: Three of the four main characters are reporters or otherwise work for a newspaper.
 * Cell: Clayton Riddell is a writer of graphic novels.
 * The Tommyknockers: Jim Gardener is a poet.
 * 1408, short story in Everything's Eventual: Mike Enslin writes non-fiction books about haunted places.
 * The Shining: Jack Torrance is working on a play and has a pile of short stories under his belt.
 * Carrie: Sue Snell wrote a book about her experiences.
 * The Green Mile: Paul Edgecombe is the narrator, a main character, and also writes a huge portion of the book.
 * The first book in the Legacy of Aldenanta series by John Ringo starts off with a clear Author Avatar sci-fi writer being called in as an expert by the government to help deal with the consequences of First Contact with aliens. A clear equivalent of David Weber also shows up in the same group.
 * The male protagonist in Breakfast at Tiffany's was a writer.
 * John Irving loves this trope.
 * The World According To Garp. Garp's first two novels have plots that are similar to Irving's first two novels. In fact, a rejection letter Garp receives for one of his stories was one that Irving received in Real Life for the same story.
 * The narrator of Irving's The 158 Pound Marriage is a semi-successful author of historical fiction. If this troper's guess is in any way correct, the novel describes but also results from an author's frustrating, year-long research trip to Vienna, which yielded no intriguing fictional narratives but did yield a hot wife.
 * Taken Up to Eleven in A Widow for One Year. Ruth Cole, the protagonist, is a successful writer. Her father, who is a main character in both sections of the book, is a writer/illustrator of Not for Children children's books. Her long-lost mother writes detective fiction.
 * The youngest sister in The Hotel New Hamphsire writes a book.
 * Kurt Vonnegut's novels have the recurring character of Kilgore Trout, though he's not exactly how the author consciously inserts himself into his stories.
 * Actually, if Trout is based on anybody, he is based on Theodore Sturgeon, of Sturgeon's Law.
 * Isadora Wing, the protagonist of Erica Jong's Fear of Flying. It was loosely based on her own life.
 * Mia Thermopolis in The Princess Diaries.
 * Jake Woods and Clarence Abernathy, respective protagonists of the first two books in a trilogy by Randy Alcorn, are both newspaper columnists.
 * In Jeff VanderMeer's Shriek: An Afterword the dual narrators are an ex-gallerist and an ex-historian respectively, and both earned their living for much of their lives as freelance writers of various essays and articles. Since the book is a fictional autobiography, the financial problems associated with the profession are often in the foreground.
 * In Greg Bear's science fiction novel Queen of Angels, the story revolves around a novelist, playwright and poet, who has just killed eight people. Another main character is also a writer.
 * Dean Koontz seems to be quite fond of this trope; to name just a few examples, the protagonist of his book Cold Fire is a reporter, and in Lightning, the main character is a novelist.
 * Henry Fitzroy, the vampire from Tanya Huff's Blood series (turned into the TV show Blood Ties), is a romance novelist. In the TV version, he writes and draws graphic novels.
 * Lily from The Secret Life Of Bees discovers and professes her talent for writing, mostly fiction.
 * Emily, of the Emily of New Moon books, knows she not only wants to be a writer, she is a writer with all of her self. The people around her can use this need to manipulate her if they want - promising her that she can go to college, no strings attached, but only if she gives up writing fiction for the entire time. And in the third book,
 * William Goldman's The Color Of Light is about this trope. It goes a bit over the top in lampshading it, though.
 * Scheherazade gives the impression of being some Arab Coffeehouse bard's ideal woman.
 * Dr. Watson is, of course, a medical professional, but it's on account of his writings about Holmes that Holmes is so well known. Of course, the stories he writes that make Holmes famous are the same ones that we read, so this could be the world's first meta example of the trope.
 * Being one of the few doubled tropes on this page, Sir Arthur Conan Doyle was also a doctor. Naturally a doctor-writer would write about a doctor-writer.
 * Bram Stoker's Dracula goes even further. It's presented as a series of journal entries and articles compiled by Mina Harker, and the construction of the book itself assists the heroes in uncovering Dracula's secrets. So the writing of the book is actually a plot point within the book.
 * Judy Abbott, the heroine of Daddy Long Legs, goes to college specifically because of her writing. Her anonymous benefactor likes a funny essay she wrote about the orphanage where she grew up, and agrees to sponsor her education so she can become a writer.
 * The narrator in Nikos Kazantzakis's stunning novel Zorba the Greek is a writer, an attribute for which Zorba often pokes fun at him.
 * The narrator of the framing story in Life of Pi is an author who wrote a historical fiction novel that should technically have been amazing, but to him was so unlikely to raise any eyebrows in book publishing that he tossed the entire manuscript. Then at a café he met someone who told him about a young Indian man named Piscine...
 * In Vladimir Nabokov's Lolita, the narrator Humbert Humbert is a literature professor, and although (to this troper's memory) he never refers to novels that he has actually published, he does tell Charlotte Haze that he was working on a novel when she finds some very suspect entries in his journal.
 * He is writing a rather large scholarly piece on the works of Rimbaud, Verlaine, and Baudelaire, which I believe is actually published early on into the novel. This is a common trope for Nabokov, at least for his English language novels; almost every one of them features some sort of writer as the protagonist. As we approach the end of his career, the number of similarities between this writer/protagonist is notably increased. Nabokov notes this, and frequently takes a poke at his protagonists for being shades of a more 'real' life.
 * According to legend, the implications that this trope presents almost led Nabokov to destroy his materials for Lolita, on the fear that people would think he was actually Humbert.
 * One of Nabokov's books actually begin with a scene the protagonist is watching out his window that he decides he wants to use to start his novel someday.
 * The lead of PG Wodehouse's Life Among the Chickens is a writer named James Garnet. Early in the story, he shares a train carriage with a pretty young woman who (unbeknownst to her) is reading his novel, and says to her father that she likes the protagonist. The following quote forces the reader to frown at the novel and go "hang a minute!"

Garnet also smiled to himself. Arthur was the hero. He was a young writer. Ergo, Arthur was himself."


 * One of Hercule Poirot's friends in Third Girl is a middle-aged mystery-writing Englishwoman, much like Agatha Christie, who tries a spot of amateur detecting. And, in accordance with the tropes of the genre,
 * Agatha Christie has several characters who are writers, including Ariadne Oliver and Miss Marple's nephew Raymond West, both of whom appear repeatedly in supporting roles throughout her stories.
 * The narrator-protagonist of The War of the Worlds is an academic author. H.G. Wells wrote a lot of non-fiction alongside his novels and short stories, though he is less-known for the former today.
 * The protagonist in Terry Pratchett's non-Discworld short story "Final Reward" is the author of a long-selling series of barbarian fantasy novels.
 * From the Discworld novels, William De Worde started off as a freelance letter writer, then later becomes a newspaper publisher and journalist in The Truth. Appropriate when one realizes that Pratchett was originally a journalist himself.
 * In Maskerade, Granny Weatherwax and Nanny Ogg travel to Ankh-Morpork after they learn Nanny's been cheated out of royalties from her risque cookbook. The throwaway gag about spelling "famine" with seven letters is a Shout-Out to the same error that occurred in Real Life.
 * In Snuff, Vimes has to meet with a famous children's book writer Miss Beedle. Walking up to her house, he muses that he has no idea what writers do at home. Possibly sit in their nightgown drinking champagne. A footnote remarks that this is completely true.
 * The protagonist of The Chronicles of Thomas Covenant is a successful writer whose life quickly turns to shit. When things start getting better, he refuses to believe it is real...
 * Both Ellie and Chris from The Tomorrow Series are writers.
 * French author Bernard Werber loves to put writers as characters: journalists and novelists are all over the place, it seems.
 * British author and cartoonist Ros Asquith has done this several times. Letty in the Teenage Worrier series (although her dream is to become a film director, she frequently mentions that she is a published author as well), Cordelia in the Girl Writer series and Flowkwee in Letters From an Alien Schoolboy are all examples.
 * An Egregious example is Jonathan Franzen's Freedom, whose story is largely told from the perspective of Patty Berglund writing her autobiography. Even though Patty knows she isn't too smart and otherwise shies away from intellectual life, she seems to write about as well as Jonathan Franzen does in the rest of the novel.
 * Although her calling in life is to be a Guardian, Mercedes Lackey creation Diana Tregarde's income comes from writing romance novels.
 * Her Author Avatar in the Heralds of Valdemar series is a historian and chronicler, as well. She only gets a speaking role in the Exile series, however.
 * House Of Leaves is a more indirect use of this trope. To quote the quote on its page, "It's a book about a book about a film about a house that is a labyrinth."
 * Betsy in the Betsy~Tacy series is all about telling stories in the early books, then naturally progresses to a writer as she grows older. She shares her passion for writing with her future husband. This makes sense, as Betsy was basically an Expy of the writer Maud Hart Lovelace, who was also married to another passionate writer.
 * The narrator-protagonist of Carol Shields's Unless is a writer and translator.
 * The Red Tree follows Sara Crowe, a writer suffering from an intense block after the suicide of her girlfriend.
 * In The Book of Joe, the protagonist is Joe Goffman, a succesful author struggling with his writer's block.
 * In Fame, there's only a single character in the entire novel who doesn't see himself as a writer or character. The rest of the cast consists of three writers, a forum addict, a number of fictional characters, a world famous actor, a man who invents his own new life, and a woman who ends up as a fictional character against her will.
 * Lord Peter Wimsey's love interest Harriet Vane is a mystery writer. And that's not the only similarity between her and Dorothy Sayers.
 * Wonder Boys -- both novel and film -- is about an English professor who is stuck in the middle of writing an endless, soul-sucking Doorstopper of a novel.
 * Charlie Bucktin, the main (but not titular) character of Craig Silvey's Jasper Jones, is an aspiring author. And so is his dad.
 * Tosca Lee's Demon: A Memoir is premised around not one, but two main characters as writers: one, an editor who has tried and failed for years to write novels, and second, a demon with a marvelous storytelling gift but no ability to physically write and publish his story. Hence, a partnership (of sorts?) is born.…
 * Kill Time or Die Trying: being based on real events most of which the authors were present, features the authors themselves as characters. Subverted, in that the fact their being writers is barely mentioned, apparently to avoid spoiling the fun of trying to figure out which characters are the authors.
 * A very literal example of this trope, Stephen Glass, former journalist for The New Republic and who is most well-known for partially or wholly fabricating many of his stories, went on to write a semi-fictional novel about a journalist who is caught fabricating his stories.

Live Action TV

 * The Dick Van Dyke Show: Rob Petrie is a television comedy writer.
 * Murder, She Wrote: Jessica Fletcher is a mystery writer.
 * While not the main character, McGee of NCIS is a popular novelist on the side, writing thinly veiled accounts of his adventures with the Gibbs Team.
 * Temperance Brennan of Bones is a forensic anthropologist who also uses her professional expertise to write books based on a "fictional" forensic anthropologist named Kathy Reichs - who is the real life author of the books upon which the show is based.
 * What's also interesting in her case is that, she honestly thinks her books are best-sellers because people are actually interested in the forensic science - not, you know, the human interactions and crimes that facilate said forensics. She is bewildered and annoyed when being interviewed about her latest book, all the reporter wants to talk about are the characters and motives instead of how interesting and true to life her science is.
 * We find out later that, had she her way, she would forgo the human interactions and focus only on the crime/science if she could; her publisher/editor/agent/whoever said it wouldn't sell, so she felt compelled to add the rest. Said "rest" comes heavily supplied by help from Angela, including several sexual positions and/or techniques.
 * The protagonist of Castle writes mystery novels for a living, and because of his connections, he gets to spend a lot of time with the police, getting inspiration while offering his own professional insight.
 * And if that wasn't enough, he writes about a writer who follows the NYPD around.
 * The two main characters of Spaced are Tim, a cartoonist (it's a bit more complicated than that), and Daisy, a writer.
 * in Just Shoot Me everyone works for a magazine. The only one in the main cast who is a writer by profession is Maya, although Dennis has shown some writing prowess, penning (among other things) at least two screenplays, a few songs, an advice column, and most of his boss's "autobiography".
 * Rory of Gilmore Girls is a journalist.
 * Sex and the City: Carrie is a newspaper columnist.
 * In both Kolchak: The Night Stalker and its short-lived retool Night Stalker, Kolchak was a reporter.
 * Thirty Rock: Liz is an Author Avatar by Tina Fey's own admission.
 * Dennis Potter was a writer who suffered from severe psoriatic arthritis. His best known work was the TV Series (later made into a movie) The Singing Detective, about a writer who suffers from psoriatic arthritis. A difference is that the writer in the TV series wrote pulp detective fiction, while Potter mostly wrote rather surreal TV series.
 * The Five-Man Band in How I Met Your Mother aren't writers by trade, but they do enjoy spending hours brainstorming sit-com joke lines. On top of that, Barney is a popular blogger, Marshall writes songs as a hobby, and Ted and Barney compose dueling poems in The Sexless Innkeeper.
 * Ted may be an architect, but he does love to wax douchey about literature and poetry.
 * During his retirement from the FBI, David Rossi of Criminal Minds supported himself as an author and lecturer. Although he is a nonfiction writer similar to the real life profiler John Douglas.
 * The father on 8 Simple Rules was a sports columnist.
 * Raymond, of Everybody Loves Raymond, is also a newspaper columnist.
 * The main protagonist of the show Bored to Death is a struggling writer who even has the same name as the creator of the show (Jonathan Ames).
 * Jerry on Seinfeld is, like his Real Life counterpart, a comedian; many episodes show Jerry struggling to write new material for his act.
 * When, in the episode "The Pitch", he and George pitch a "show about nothing" to NBC execs, this is a direct parody of the creation of the show by the real Jerry and Larry David.
 * Hank Moody from Californication
 * Gabrielle from Xena: Warrior Princess may not have been a writer in the same way the others are, but as a bard and chronicler of Xena's adventures, it's probably as close as we get. There's even an episode about her writing a story about Xena.
 * Virgil, Joxer's son, is a poet, much like his real life namesake.

Musical

 * Trixie True Teen Detective has Joe Sneed, a writer who wants to write hard-boiled detective novels, but is stuck working in a syndicate stable writing perky-girl-detective stories instead.
 * The Musical of Little Women uses this, of course, following the book, but it's amusingly evident when Jo, in the song "Weekly Volcano Press," supposedly reading aloud her story, reads something that sounds more like a script for a musical ("The forest is dark and spooky. Clarissa enters, her clothes in disarray...") than a past-tense short story normally would.
 * Mark from Rent is a would be film maker who has written a few screenplays. (Which he burns.) His friend Roger spends the musical singing about how he wants to write a song.
 * The protagonist of City of Angels is a writer trying to adapt his novel into a Film Noir. The antagonist is a meddling executive.
 * Occurs twice in the canon of Stephen Sondheim: the Broadway songwriting team of Franklin Shepard and Charley Kringas in Merrily We Roll Along, whilst both Georges in Sunday in The Park With George are artists who struggle to be understood and accepted by their peers, much like Sondheim himself.
 * Cliff Bradshaw in Cabaret - naturally enough, because the show ultimately derives from novelist Christopher Isherwood's memoirs kept while he was living in Weimar Berlin.

Newspaper Comics

 * Jon Arbuckle of Garfield was specifically identified as a cartoonist in early strips, at least before he essentially became a full time Cloudcuckoolander loser guy. In the cartoon, however, his profession regularly drives the conflict in the plot.
 * The father in Family Circus is also a cartoonist.
 * Michael Patterson of For Better or For Worse. His first novel is a best-seller.
 * Sydney in Dykes to Watch Out For is an academic writer and there have been other minor characters like Deidre and Anjlai who write but main character and semi-Author Avatar Mo has creator Alison Bechdel's bibliophile tendencies instead of being a writer herself.

Theater

 * Theater in general falls into the same trope. Many plays are written about writing or staging a play.
 * Noises Off

Video Games

 * The protagonist from the Darkseed games is a writer.
 * Toonstruck stars the aptly named Drew Blanc, a struggling cartoonist.
 * Gabriel Knight writes supernatural mysteries which are "loosely based" on his own experiences.
 * Comix Zone is about a comic book writer whose Big Bad managed to trap him inside his own comic book.
 * Alan Wake is a Stephen King-esque writer who gets caught up in a scenario similar to his books. Penny Arcade explains.
 * The game also has a more direct invocation of this trope by having a character that's game developer (who's in an insane asylum... with some pretty fun dialog). Interestingly, this happens very rarely in video games which seems to imply that video games seem to be one of the media that bucks the trend. Why this is is another question.
 * Harry Mason from Silent Hill. Possibly not a very good one.
 * Adrienne Delaney from Phantasmagoria is a best-selling novelist, particularly well known for her book Blue Moon Rising.
 * The protagonist of Scratches, Michael Arthate, is rising horror writer; In Last Visit the protagonist is an unnamed reporter.
 * Segagaga is about running SEGA as a company, producing and distributing games. Played with, however, as the characters in the company's games are real and help with development (Amigo from Samba De Amigo is a high-level programmer, for instance), the development process itself plays out like a normal video game, and past SEGA systems are actually spaceship-like weapons.

Webcomics

 * Slick from Sinfest is sometimes seen trying to write a literary masterpiece. He also does poetry slams in the earlier strips.
 * Davan of Something Positive is, for a time, the writer of a webcomic. He also has a regular job as the personal assistant of a theatrical producer; this job on occasion makes use of his writing skills, such as when he had to rewrite a show's script.
 * The Shakespeare character in Irregular Webcomic works in an office doing some sort of writing, and writes Harry Potter Fan Fiction on the side.
 * Well, he is William Shakespeare, you know.
 * Lynda Levac of Penny and Aggie is a columnist for a parenting website.
 * David in Living With Insanity.
 * In the modern arc of Arthur, King of Time and Space, Arthur writes a webcomic, as did Merlin.

Web Original

 * Not writers, but the cast of Marble Hornets is mostly made of film students.
 * A Cracked article discusses how Hollywood films get other professions wrong by extrapolating from the experiences of Hollywood writers: 6 Things Movies Love to Get Wrong About the Workplace

Western Animation

 * Andy French of Mission Hill works at a mattress store, but he's an aspiring cartoonist. At least one episode deals with his discouragement over all the rejections he's gotten sending his comics to various magazines.
 * Ginger Foutley of As Told by Ginger was a writer. The show specified that she was a gifted poet, but it was inferred that she was an all-around talented writer.
 * Mikey on Recess is a writer of epic poetry.
 * Doug is a writer and cartoonist, in fact many episodes open and close with him writing in his journal.
 * Daria is a talented writer, while her best friend Jane is an artist.
 * Brian from Family Guy writes as a hobby (albeit he's not very good).
