Loads and Loads of Writers
Creating works of media and fiction is anything but easy. From sustaining plot development to proper trope usage (and avoidance), it's no wonder why the whole field in general is perceived to be an ongoing minefield. But every once in a while, a concept comes along that is much too big for one or two people to handle on their own, particularly a soon-to-be Long Runner. At this point, the only plausible solution is to hire a group of writers to help you out with it, since the main creator's own writing isn't always going to be up to the expectations of the viewers and fans. Since literature, manga, and web comics are almost always fully written by one or two people, don't expect any examples of this to exist from those mediums (though see Round Robin).
Comic Books
- DC Comics often does a weekly strip that is written by a variety of authors but is coordinated by a single one.
Literature
- The Amazing Adventures of Kavalier & Clay used this In-Universe when they pulled an all-weekender to prepare the first issue of Amazing Midget Radio Comics.
- The 39 Clues
Live-Action TV
- Television sitcoms in general seem fond of having a stable of writers.
- Soap Operas are known for having a half-dozen writers credited for a single 22 minute episode.
- Sesame Street
- Doctor Who.
- The revived series is on its sixth season, and Steven Moffat is the only man who's written at least one episode every season. He at best writes six or seven of them per thirteen-episode season, and he's the head writer.
- The classic series fit this profile even more. Since with a few exceptions the producers didn't write scripts, a wide variety of staffers and freelancers did the writing. There were some notable recurring writers like Robert Holmes and Terrence Dicks.
- Mystery Science Theater 3000 was written by basically everybody working on it. Mike Nelson was referred to as Head Writer, which in practice meant he put together everyone's quips into a single script.
New Media
- Forum Roleplays tend to have this because there are Loads and Loads of Characters and each one needs someone to play them.
Theatre
- Oh! Calcutta! had sketches written by (among others) John Lennon and Samuel Beckett.
Western Animation
- The Simpsons
- Family Guy, although that doesn't stop people from blaming Seth MacFarlane for everything that they find wrong with the show.
