Game Grumps is the YouTube channel created by Jon Jafari and Arin Hanson, where they play games while doing commentary. After about a year of Game Grumps, Jon left the show, and was replaced by Danny who also stars in the spin-off show Steam Train with Ross, who joined shortly after Jon's departure. The channel consists of many series: Game Grumps, Game Grumps VS, Game Grumps Animated, Guest Grumps, Steam Train, Steam Rolled, Ghoul Grumps, and Scream Train .
The Game Grumps began as a result of an argument between Arin and Jon. They were playing Super Smash Brothers Brawl with friends and had an intense debate about whether the characters Wolf and Fox were clones or not. When someone complained that the two should stop being so grumpy over the game, Arin suggested he make a podcast called Game Grumps, and the idea evolved into the creation of Game Grumps.
The Game Grumps channel was created on July 10th, 2012, and their first video was posted on July 18th. Since beginning the channel, they have accumulated a huge fan following from Egoraptor fans, JonTron fans, and gamers in general. The Game Grumps play games and commentate on them in the same vein of a "Let's Play" channel, though they usually insist they aren't a Let's Play channel (there has been at least one occassion where Jon refers to GameGrumps as a Let's Play channel). Given the fact that the Grumps do not complete most games they begin, this holds true. The Grumps discuss various topics, usually revolving around game they are playing, game design, their channels and social lives, and pop culture. Currently, the channel has over 1,000,000 subscribers and over 200,000,000 total video views.
Ever since the beginning of Game Grumps, they had a strong and creative fanbase. Their fans have made a lot of Game Grumps-related content. Game Grumps fans have made a lot of fanart for the Grumps. The fanart is generally either an illustration of a moment from an episode, or simply drawings of Jon and Arin. The fans have also made a notable amount of Rule 34 fanart of the Grumps, which they have acknowledged. Some fanart has been posted on the Game Grumps Facebook page. Another form of fan content is remixes. The remixes are generally created by editing audio from Game Grumps episodes. The first notable example of a fan remix is Waterflame's pause balls remix, which was mentioned and sung in an episode of Game Grumps. Fanmade Game Grumps Animated have become a very common creation among fans. These animations show parts of the Game Grumps' playthrough, generally either placing Arin and Jon inside the video game, or showing them on their couch playing the game. These animations were done even before Arin had made some for the Game Grumps channel, although they became more common afterwards.
Early in Game Grumps, they generally played games Jon or Arin had played before, and wanted to share with the other, such as Jon's Banjo Kazooie, and Arin's Mega Man 7, or both had played and enjoyed, such as Kirby Super Star. In September 2012, the Game Grumps began receiving games in their PO Box from fans, and even more as time went on. Their variety of games became more diverse, and the amount of time spent playing each game generally decreased; many games played were only one-offs, or series only lasting about three episodes.
When Game Grumps began, Jon edited the videos, and he and Arin shared management of the Game Grumps channel. Late in September 2012, Barry took over the role of editor of Game Grumps, as well as every role besides the actual recording, including uploading videos and managing playlists. This was done to allow Jon and Arin to focus more on their main channels. Barry copied Jon's style of editing to keep his role a secret, in fear that fans would not feel comfortable with somebody else editing the videos. Fortunately, fans responded positively to Barry, and he has become as popular as Jon and Arin.
In January 2013, the Game Grumps attended their first convention, MAGFest 11 (although Arin had gone to conventions before, without Jon). They held their first Game Grumps panel, where they answered many questions about the show, and announced many upcoming events. Whether they will be hosting any more panels is unknown; Jon wants to, but Arin is unsure if he feels like going to any more conventions.
On June 25, 2013, it was announced that Jon is leaving the show, and that Danny is taking his place. On the same day, the Game Grumps channel received a spin-off show, Steam Train, starring Danny and Ross.
On August 23, 2013 began Steam Rolled, originally a competitive version of Steam Train, similar to Game Grumps VS. On the first episode, Quake III Arena, Barry joined as a player. Suzy also joined Steam Rolled shortly after this episode, on August 26, playing Mario Party 4.
On October 25, 2013 a temporary Halloween themed Game Grumps and Steam Train series called Ghoul Grumps and Scream Train began. There is no indication if this cosmetic change will be an annual event that occurs every Halloween.
