GTLive

GTLive is a livestream hosted by MatPat Patrick typically on Fridays at 10:00 AM Pacific Time, with prerecorded videos on Mondays and Wednesdays. As of 2019, there have been more than 500 GTLive streams.

History
On August 26, 2015, Matthew Patrick and several other YouTubers collaborated to have a discussion over the Five Nights at Freddy’s franchise. The stream was broadcasted from The Game Theorists channel, but was later unavailable to view. The Theorist channel continued to have regular live streams, mostly featuring unscripted gameplays by Matthew and Stephanie.

On September 14, 2015, the GTLive channel, fondly called Archiveland, was made. The plan was to upload "Complete Streams" and "Highlights". Complete Streams were mostly unedited versions of livestreams, and Highlights were videos comprised of funny moments and humorous editing using footage from the streams. After October of 2015, the channel only uploaded the complete live streams. In July 2017, the channel experimented with editing the complete streams in order to fit an average stream length of 20-30 minutes. By September 2018, it was decided that only GTNotLives would be this length.

On October 3-24, 2016, the Monday streams became part of YouTube Gaming Primetime and were scheduled to take place from 3 pm to 5 pm PST on Mondays. It also included a voting mechanism, which could be to conduct quick polls. The streams concluded their spot on YouTube Gaming Primetime.

On January 16, 2017, the channel officially reached one million subscribers.

On April 13, 2017, the channel (along with The Game Theorists, The Film Theorists, and other channels that were in the same network) was hacked by the hacker group OurMine. As a result of being hacked, all their videos were changed to "#OurMine - https://youtu.be/IdJuVgR_-7M (Read the Description)" as the title. But shortly after the same day, all 3 channels were restored with the correct titles and descriptions.

On October 29, 2018, the first livestream was hosted on the GTLive channel and that has been the standard since.

On February 19, 2019, the first GTeaLive was hosted on the GTLive channel and Matt and Stephanie suggested doing it weekly.

On March 8, 2021, Stephanie announced that she would no longer be making regular appearances on GTLive, in the interest of personal and professional endeavors. She made her final official appearance on March 12, 2021, with the promise of occasionally visiting for videos and livestreams.

Format
The streams usually consist of an introduction, gameplay of a featured game or challenge, and a conclusion or analysis of the game. Games are often coordinated by theme and day of the week, with the two longest lasting being “Mario Maker Wednesday” and “Thank Goodness It’s Scary Games Friday”.

The Science Blaster intro will play to start off the stream, although early streams didn’t have this feature. Afterwards, the hosts will talk a little about their day and explain how to engage with the stream (via #GTLive on Twitter and through the YouTube live stream’s chat). Matthew and Stephanie will then introduce the game that they will be featuring during the stream.

During the Let’s Play segment, the hosts will play the games entirely unscripted and with minimal knowledge beforehand. While this does often lead to a lack of progress in the game, MatPat and Steph make up for it through both comedy and commentary, and by offering their genuine reactions towards games. When faced with games with multiple endings, the GTLive hosts will usually get the normal ending first and will then attempt to get other more plot-relevant endings.

To conclude the stream, Matthew and Stephanie will talk about their thoughts over the game and their own experiences. Announcements about recently released videos and events will occur here as well. They will then finish the stream by saying, “That was just a stream, a live stream” and then say good-bye to people in the chat.

Recurring Features
Several features have been defined through appearances in numerous live streams. They include:
 * Clap-and-a-half: a literal "clap and a half" which Matthew reclaimed from his seventh grade Social Studies teacher.
 * Stab-and-a-half: an alternative version of the clap-and-a-half which was introduced during GTLive’s playthrough of the popular indie horror game Fran Bow. It was first introduced in the episode "QUEEN of Blood - Fran Bow Part 4". The phrase was originally coined by a viewer in the chat by the name of aaron2718. It usually appears during a scary game, or during “Scary Games Friday”.
 * Mature Stream: This label was created for games with questionable or adult content, in order to warn viewers. It is occasionally used humorously or ironically.
 * BlameJason: a now-common hashtag on Twitter, used to "blame Jason" for technical issues during the stream, or more extensively used to cover anything at all going wrong in a livestream.
 * BlameChris: an alternative to "BlameJason" except blaming Chris for problems.
 * Protips with Stephanie: unhelpful or incredibly obvious tips from Stephanie. They were often featured in the “Highlights” videos, and had both a title card and theme-song.
 * HufflePat, Stepheryn, Jasonclaw, and Chrisindor: a friendly “competition” between the four cast members of GTLive, based on the houses within Harry Potter.
 * RagePat: usually used when playing rage games or during frustrating levels. His hairstyle often gets tussled when upset, leading to the also common phrase of ‘rage hair’. Variants of the name (not always including "rage hair") have included "MadPat" and "SaltPat".
 * "Stephanie never checks the chat/Twitter!": referring to the fact that in the past Stephanie rarely checked the chat or Twitter during the live streams. She has since become better about this, but it is still a very common thing to be said during a stream.
 * LatePat: the live streams often start after the official time of 4:00 PM PST, causing fans in the stream to voice their frustrations online.
 * FatPat: this phrase is often used during games that require motion controls or on streams that feature eating.
 * Notification Squad: fans who use the ‘Notification Bell’ on YouTube to be notified about live streams or upcoming events.
 * Lines or songs from a Broadway play: Popular ones featured in the past have included Fiddler On The Roof, Brave Sir Robin Ran Away and Someone Oughta Open Up A Window.
 * "Pelvis First/Done Got Scooped": A reference from the Five Nights at Freddy’s: Sister Location Custom Night streams, where the Purple Guy walked at an odd posture after the incident in the Scooping Room. This phrase has shown up surprisingly often since its first coining.
 * Unscented Lotion: referring to the Cloudland VR: Minigolf stream, where Chris was revealed to have asked for unscented lotion as his Christmas gift.
 * Garibaldi Smell: a reference to a confession made by David Garibaldi about how he smells during the Pictionary live stream.
 * Don't be a Koala: during the Life is Strange streams, it was explained that the character Chloe behaved much like an insolent koala. Matthew and Stephanie's disdain with the character resulted in this phrase.
 * Yiffing: to "yell and sniff at the same time", a definition given by Stephanie during the Dayshift at Freddy's streams. Not knowing the definition of the term "to yiff", she came up with her own definition. The term in fact relates to the sub-culture of the Furry Fandom.
 * Sprinkler time: After coming back from their India trip to discover their lawn dead, Mat and Steph decided to make 4:45 pm sprinkler time to try to revive their lawn during live streams. It has then turned into a celebration in the chat and twitter with viewers sending cheers and water emojis.
 * Coded Message Sign: A sign with a coded message can be found in the background of every stream and changes every time someone solves it.
 * Archive Land: More so used by the chat/audience, however still used and frequently mentioned by the GTLive crew, is a synonym for the archive channel in which live streams are posted after the original stream has ended. Those who are unable to attend the live stream (due to time zones or otherwise) for a long time, using the archive channel to watch GTLive and would say they are from 'archive land.'
 * Unlistedland: Similar to Archive Land and a relatively new term that is only really used by the audience, is for when people watch the full (now unlisted) live streams through their notifications.
 * Spoiler Stephanie: A nickname MatPat gave Stephanie, derived from her tendency to unknowingly spoil the plot of tv-series, movies and games. This is sometimes followed by the two debating what exactly counts as a spoiler.
 * Face-five: A variation on high-five where Matt or Steph place their handpalm against the other's face.
 * Unbranded Diet Soda X: Used by Matpat whenever he drinks diet coke on stream to poke fun at Coca Cola for never sponsoring him regardless of his self proclaimed 'diet coke addiction'

Regular Guests

 * Peepachu: a yellow cushion shaped as a bunny Peep. Speaking only in ‘peepas’, it usually provides comfort during live streams or sits on the shelf in the background as a decoration.
 * Septic... Eye?: a Jacksepticeye plush that took Peepachu's place on the couch after Peepachu went to the shelf.
 * Drama Llama: a fluffy, white alpaca toy from Peru. It initially appeared on the Last Impact - LATE NIGHT stream, and serves as an indicator of complaints on its live streams.

 * Jackachu: a pumpkin cushion that occasionally appears during streams that take place around Halloween.
 * Safety Topiary: a small bush that appeared during the Blameless stream. It was a popular one time guest, but was unfortunately broken by Matthew shortly after the stream.
 * Safety Pumpkin: a pumpkin that appeared during the Dirty Minds and Dayshift at Freddy's streams. Stephanie used it to hide behind when she became uncomfortable.
 * Boo: a light up Halloween decoration who appeared during the eponymous holiday. It was unlit during its first live streams, but gained an extension cord in later appearances.

Complete Streams
This is a list of complete streams that have been produced by The Game Theorist channel. Most of the streams have been uploaded to the GTLive channel, with very few exceptions. In addition, several of the streams remain available to be viewed but are currently set as "Unlisted" on The Game Theorist channel.

When the streams are uploaded to the GTLive channel, they often undergo a slight name change. The list below states their original stream name as viewed on The Game Theorist channel. If the name is unknown, the name used as their GTLive upload will be used. In addition to this, the streams for 2016 introduced an occasional reoccurrence. The playthrough of Pony Island, the last episode of The EarthBound Halloween Hack, and the entirety of the story mode of Five Nights at Freddy's: Sister Location were filmed within their own streams, but were considered too long to upload as their own long videos. Because of this, the live streams were later recut and uploaded as several separate videos.
