Rooster Teeth was founded by Burnie Burns, Matt Hullum, Geoff Ramsey, Gus Sorola, and Joel Heyman in 2003. Burns created voice-over-enhanced gameplay videos of Bungie Studios' popular first-person shooter video game Halo: Combat Evolved. Eventually, these videos led to the creation of Red vs. Blue, which premiered in April 2003 and is still in production, making it the longest-running web series of all time. The production team also focuses on projects such as reality shows, video game development, entertainment news programs and podcasts. Rooster Teeth will release its feature film debut Lazer Team, a science fiction action comedy film in 2016.

The company's videos are released on its website and YouTube, on which it controls a multi-channel network and maintains over 8.3 million subscribers and over 4.1 billion video views on its primary channel, as of December 2015.
