Jonathan "Jon" Jafari (born 24 March 1990), more commonly known on the internet as JonTron, is an entertainer and the co-founder of the show Game Grumps, alongside his friend Arin Hanson. Besides Game Grumps, he is known mostly for his game reviews and being part of the community known as NormalBoots. Jon's tenure on Game Grumps lasted for 342 days (18 July 2012 - 24 June 2013) before leaving. Jon started his show in 2010 with a standard review of the video game Daikatana, but he didn't gain internet popularity until he retooled the series with a more original style. After a fan posted Jon's "DinoCity BRO!!!" video on Reddit with the description "After watching this, video game reviews really aren't the same anymore," Jon's popularity boomed. This is also when Jon's videos were first brought to Arin Hanson's attention. Jon is the co-creator of the NormalBoots website, alongside PeanutButterGamer. NormalBoots was shut down as YouTube's partner program became a much better way to earn money than ad revenue on NormalBoots. However, it has recently been resurrected due to uncertainties surrounding the long-term viability of being dependent on ad-revenue from a site that is becoming increasingly mired in copyright controversies that could potentially end up shutting down channels such as Jon's. Jon has appeared in videos of a fellow NormalBoots member Continue?. He has also done many voiceovers for episodes of Did You Know Gaming?. Jon started contributing to Channel Awesome in 2011, working on the subdivisions "That Guy With The Glasses" and "Blistered Thumbs." Jon is also a member of The Game Station, now rebranded as Polaris. Jon is educated in musical theatre. He will occasionally display his musical talent in videos that he produces, as well as many episodes of Game Grumps. Jon made a cameo appearance in a Pepsi commercial with Mike Tompkins, where he appeared along with many others singing the tune "Take Me Out to the Ball Game" in honor of the 2013 World Series. The original publisher of the video, Maker Music, had posted in the video's description a link to Jon's Youtube page, asking fans to get him to sing the National Anthem for the World Series.
