TheSpeedGamers
TheSpeedGamers (also abbreviated as TSG) are a group of gamers based out of Arlington, Texas, who raise money for various charities. They accomplish this by streaming live marathons of video games played over Twitch.tv (formerly Justin.tv). The group was founded by Britt LaRiviere in early 2008 and still hosts marathons regularly. Viewers can interact with the commentators and other viewers via IRC chat on Justin.tv. The group has raised over $535,000.00 for at least 16 different charities.
