Rotten Tomatoes is an American review-aggregation website for film and television. The company was launched in August 1998 by three undergraduate students at the University of California, Berkeley: Senh Duong, Patrick Y. Lee, and Stephen Wang. The name "Rotten Tomatoes" derives from the practice of audiences throwing rotten tomatoes when disapproving of a poor stage performance.

Since January 2010, Rotten Tomatoes has been owned by Flixster, which was in turn acquired by Warner Bros. in 2011. In February 2016, Rotten Tomatoes and its parent site Flixster were sold to Comcast's Fandango. Warner Bros. retained a minority stake in the merged entities, including Fandango.
