Red vs. Blue, often abbreviated as RvB, is an American comic science fiction video web series created by Burnie Burns with his production company Rooster Teeth Productions. The show is distributed through the Internet on Rooster Teeth's website, as well as on DVD, Blu-ray, and is syndicated through the El Rey Network. The story centers on two opposing teams of soldiers fighting a civil war in the middle of a desolate box canyon (Blood Gulch), in a parody of first-person shooter (FPS) games, military life, and science fiction films. Initially intended to be a short series of six to eight episodes, the project quickly and unexpectedly achieved significant popularity following its Internet premiere on April 1, 2003. The series consists of thirteen canonical seasons and five mini-series. Red vs. Blue is the longest running episodic web series.
