If You Can Read This...

Frequently characters will have to read something onscreen as part of the plot. It could be anything from a newspaper to a book to a computer monitor. Back in the days when TV sets used CRTs [cathode ray tubes], that text was largely unreadable due to their low resolution.

The march of technology has now replaced the old CRT with LCD flat panels and plasma screens with incredible resolution where even the smallest details in an image are discernible. This can be anything from informative to embarrassing, depending on whether the producers took this new technology into account when composing any onscreen text for the characters to read.

Anime and Manga

 * Neon Genesis Evangelion uses the show's scripts to create text for various purposes.
 * In an early episode of Gundam Wing, the computer screens with Heero's medical data show text from the readme file for Photoshop's TWAIN plugin.
 * In the 2003 anime version of Fullmetal Alchemist, any book on alchemy shown onscreen is copied from Dungeons & Dragons player's manuals on alchemy. Evidently, Amestris runs on a D20 system.

Film

 * There is a eye chart in the background in Return of the Living Dead where the letters read "Burt is a slave driver and son of a bitch who's got you and me here." (Burt was one of the people who opened the Trioxin barrel in the beginning.)
 * The newspaper articles in Fight Club all have the same nonsense text, whether the headline is "Fountain Befouled" or "Feces Catapault Seized" or "Stolen Lab Monkey Found Shaved".
 * The Daily Prophet newspapers in the Harry Potter film releases.
 * A surveillance console displaying a lot of scrolling small text in A Scanner Darkly is actually scrolling through Blade Runner's screenplay...in screenplay format!
 * American Beauty has a sign in Lester Bernam's cubicle at work that simply reads "Look Closer." This was just something the set designer just felt like decorating the set with. Director Sam Mendes noticed this after seeing the footage in the editing room, and the phrase "Look Closer" would eventually become the movie's tagline.
 * The Star Wars prequel trilogy (and other EU sources) does this quite frequently...in an alien alphabet, called Aurebesh. If you transcribe each character for its Roman equivalent, it is just plain English. Some examples make sense in context (such as the screen of Anakin's Naboo Starfighter in Phantom Menace) but most are simply inside jokes made by the creators of the material.
 * The license plates in The Fifth Element read "New York, the 'Fuck You' State".

Live Action TV

 * Star Trek: The Next Generation's set designers had one heck of a sense of humor, and built in a ton of Shout-Out in-jokes which they expected no one else to ever see. Then the Technical Manual and DVDs came out, and the rest of us got to see them.
 * The dedication plaque on board the Enterprise-D that the engines were built by Yoyodyne, and listed many of the producers and writers as members of the engineering team who designed and supervised its construction.
 * The warp engine schematic in Main Engineering also labeled one obscure part of the warp reactor the "Oscillation Overthruster".
 * Also, the sickbay monitors had one bar labeled "med ins rem" for "medical insurance remaining".
 * The main schematics on the bridge and in Main Engineering showing the deck layout of the ship had other in-jokes, from a DC-3 prop plane in the shuttlebay, to a hamster wheel in the main warp reactor room.
 * A list of shuttlecraft barely visible in the shuttlebay set lists shuttles with unlikely names such as "Indiana Jones" (named for the famous archaeologist) and "Pontiac" (named for the car company whose commercials at the time featured voice-overs by Patrick Stewart).
 * There was an episode where someone calls up a list of names on the display, and most of the list comprises of the actors who have played a certain Doctor.
 * Many of the pipes and ducts in the Jeffries tubes and inside the walls were labeled as "GNDN", an acronym for "Goes Nowhere, Does Nothing". Tiny labels elsewhere on the set featured the birthdates or initials of various members of the behind-the-scenes crew, or short poems or snippets of lyrics to songs from The Beatles to the theme tune from Gilligan's Island.
 * The LCARS displays are also shown to have formerly indiscernible markings on them. It's generally numbers and letters placed in some esoteric order to give the illusion of specific purpose, but the detail is remarkable nonetheless.
 * The Promenade Directory on Deep Space Nine continues the fun with entries such as:
 * The Banzai Institute
 * Jupiter Mining Corp.
 * Millyways
 * Sirius Cybernetics Corp.
 * Spaceley Sprockets
 * Tom Servo's Used Robots
 * Yoyodyne Propulsion Systems
 * Along with references to production staff. (Berman's Dilithum Crystals, Chez Zimmerman, etc.)
 * This ultimately lead to a "Sure, Why Not?" moment on Star Trek: Enterprise. Enterprise was the first Trek series shot and broadcast in true High Definition, which meant that LCARS computer readouts were legible on screen. The production crew didn't think this was the case and proceeded to write out a complete history for Captain Archer on a computer screen for an episode involving time travel and the infamous Mirror Universe. Details included how he was eventually promoted to Admiral, was elected President of the Federation, and died peacefully in his sleep the day after he witnessed the launch of the U.S.S. Enterprise NCC-1701. After fans posted screenshots of the entries online, the writing staff was left with no choice but to canonize the details, whether they'd planned to or not.
 * In the first season of Buffy the Vampire Slayer, an invisible girl is (eventually) taken by the government and put in a classroom with other invisible children. They are asked to open their textbooks. We learn today's lesson will be on infiltrating a cult compound to assassinate its leader... the textbook is readable in DVD format, and consists of the lyrics to "Happiness is a Warm Gun" by The Beatles.
 * The final challenge of The Amazing Race 16 required the teams to place psychedelic posters of the eliminated teams in the order of their elimination. They also had to place three posters representing the three non-elimination legs. These posters featured host Phil Keoghan's complete Opening Narration that was played along with the show's opening theme in Season 1.

Video Games

 * A computer monitor in Mirror's Edge displays a humorous personal email of someone saying he pities whoever has to monitor his porn usage.
 * The Guardian Legend: All of the exposition is given to the player in the form of giant floor monitors.
 * Vexx has numerous instances of text in the game's Fictionary slash Substitution Cipher, Asataran. The longest of these is a very lengthy book title. If you actually take the time to translate it (not easy, since no translation guide is provided with the game manual—you've got to piece it together yourself—and the texture is blurred)--the title of the book turns out to be
 * Left 4 Dead has graffiti all over the place. In Left 4 Dead 2, you can even find some by Frank West!
 * The computer screens on the desks you pass in the later half of Portal display the cake recipie later said by the second Personality Core.
 * In Half-Life 2: Episode 2, at least one computer screen within the missile silo displays the numbers from Lost.
 * The occasional tactical display in the background of mission briefings in Wing Commander IV had scrolling poetry.

Webcomics
"I prepared explosive runes this morning"
 * In-universe example: Vaarsuvius of Order of the Stick is fond of inscribing his/her Explosive Runes spell with extremely small words, such that its intended victims have to lean really close to read them, with hilarious results.

""Guess what spell I cast before giving this to the bird.""
 * Turned into a Crowning Moment of Awesome when s/he uses it on, gives it to his/her raven Familiar, and has it flown out over . Xykon catches the raven, and notices the purple text.

"Aldran's Letter: P.S. Guess what spell I prepared this morning? Explosive Ru-*BOOM*"
 * Anti-HEROES: In a Shout-Out to the Order of the Stick example above, Aldran casts Explosive Runes on a letter to Eldhin. Eldhin is Genre Savvy enough to let his annoying teammate read it aloud to him, and is grinning as she reaches the end. The strip is titled "We had to use the joke eventually".

Western Animation

 * The various background signs, boxes, and papers in Rugrats often contain amusing jokes and gags, as well as Continuity Nods. One memorable box is for "Unsweetened sugar."
