TheSpeedGamers

TheSpeedGamers (also abbreviated as TSG or TSG.TV) is a group of video gamers based out of Arlington, Texas, who raise money for various charities. They accomplish this by streaming live marathons of video games on Twitch (formerly Justin.tv). The group was founded by Britt LaRiviere in early 2008 and still hosts marathons regularly through the year. Viewers can interact with the commentators and other viewers via chat on Twitch. The group has raised over $845,000.00 for more than 20 different charities.
History.
Britt LaRiviere founded the group in March 2008. LaRiviere originally imagined the site as a source for gaming reviews, but over time, the idea evolved into forming a marathon group. Finally, they decided that if they ran marathons, then they should do it for a worthy cause. They adopted a Speedrun mentality and ran their first marathon, with a Zelda theme. Since then, the group has continued on for over nine years, hosting multiple marathons and still going strong .
On January 24, 2014, TheSpeedGamers re-branded themselves as TSG.TV with an ongoing overhaul of their website, forums, and other features. To mark the re-branding, the group did an unannounced 24-hour marathon of Sonic and Mario games, raising money for Mercy Corps. Donors had the option to apply their donation toward a total for Mario or a total for Sonic. At the end of the 24 hours, the respective totals were applied as a handicap system for a 40-minute computer-controlled Super Smash Brothers match between Mario and Sonic. The winner of that match would be the franchise for the December 2014 72-hour marathon, raising money for the Rocking H Ranch. Sonic won both the significant majority of the donations and the match, and the December marathon was for the Sonic the Hedgehog franchise.
TSG 24/7 and Streams.
Starting in February 2011, TheSpeedGamers started a 24/7 stream. Unlike marathons, no money was being raised. Also unlike marathons, games weren't continually being played. Instead, various music was played while the TheSpeedGamers' fans can chat in the chat room on Justin.tv. For a couple hours each day, Britt or Chase played games as part of an ongoing Let's Play. For the 7 days of the week, they usually played a different game each day. Then, the next week they picked up where they left off the previous week, thus making it a once a week Let's Play update. As of the end of the Metroid Marathon 2011, TheSpeedGamers stopped the 24/7 streams until further notice.
On Labor Day 2011, TheSpeedGamers once again started TSG 24/7. In the fall of 2011, TSG 24/7 became TSG Present!, a more occasional stream than the previous continuous efforts.
