Screamer

The term screamer, also referred to as a jumpscare, is used to describe a game, video, website, or program, that makes the user concentrate on the screen, and then has an unexpected change to scare or startle the viewer(s). Most of these screamers also use loud sounds or screams to increase the effect (hence the name Screamer). Some examples of screamers are The Maze by Jeremy Winterrowd, Anne.jpg, Ghost Caught on Tape, and the K-fee commercials. Screamers often have a scary image and a loud scream, per example, Regan MacNeil from The Exorcist movie. In some cases they have startling or disgusting images, and these are called shock sites. They can also be considered screamers since they do surprise the user.

Origins
Screamers have been around since as far as the early 1970s, and slowly started to make surface on the web in the 2000s. The first screamers to be aired on television were part of an advertising campaign named Wide Awake from K-fee, for their new coffee drink called Turbodrink. The nine ads consisted of a peaceful scene with soothing music, but at some point in the ad, the scene gets briefly interrupted by either a zombie or a gargoyle screaming at the camera, followed by the company's slogan and the product.

Popular Culture
Because of their reputation as clever trolling tools and pranks, screamers have been featured quite recently in works of fiction and also in some well-known cartoons.

The Amazing World of Gumball
In the Cartoon Network animated series The Amazing World of Gumball, the episode named "The Internet", parodies the K-fee advertisements. In one scene, Gumball and Darwin appear randomly browsing the web while watching videos. Among these videos, they come across what is implied to be the K-fee Car ad. Gumball watches the video, commenting on the white car driving through the hills and staring closely at the screen, when suddenly the loud scream is heard, causing him to have an intense reaction which gets recorded and posted to the web. The rest of the episode involves Gumball trying to get rid of the video about his reaction, which has given him unwanted fame.

In the episode "The Spoiler", when Anais wants Gumball to take her to a horror movie, Gumball pulls a prank on both her and the audience by having the screen suddenly cut to a picture of a real-life piranha with its mouth fully open alongside a screeching noise. The screen then cuts to Annais white with shock while Gumball sports a smug grin.

Gravity Falls
In the Disney animated series Gravity Falls, the episode " Summerween" also refers to screamers. After many failed attempts at scaring two kids who have been coming to the Mystery Shack for trick 'n' treat, Grunkle Stan asks them what they find scary. One of the children shows him a video in his smartphone which says "Watch closely". It then shows a cute kitten, which is abruptly cut by a screaming demonic face, scaring Stan and causing him to have a nervous fit.

Five Nights at Freddy's
Jumpscares are the main bulk of Scott Cawthon's well known videogame franchise, Five Nights at Freddy's.

Drawn Together
In the Comedy Central animated series Drawn Together, the episode Spelling Applebee parodies the flash screamer Where's Waldo?. In one scene, Princess Clara disguises herself as Waldo and tells Captain Hero before she disappears into the crowd:  You know where to find me ''. ''After a while, the screen cuts to a close-up picture of three monstrous-looking aliens, accompanied with a piercing screech. Earlier, The image with the screaming aliens appeared during the Foxxy Love montage in the same episode.

Reactions
As screamers made surface on the web, more reaction videos were being posted and eventually became a trend on the Internet. The concept of a reaction video is to get someone to play or watch a screamer while recording their reaction.

The first reaction video to The Maze was uploaded to YouTube by the user CantWeAllJusGetAlong, on May 20th, 2006. In the video, a young kid, Justice, is playing The Maze. Then, he gets surprised by the screamer. Shocked, he starts screaming and repeatedly hitting the computer screen. He then runs to his stepdad, Chad, and starts crying. As of June 2015, the video has almost 30 million views.
