WASHINGTON- Online movie community website Flixster.com said Monday it has purchased popular movie review site Rotten Tomatoes from IGN Entertainment, a division of Rupert Murdoch's News Corp.

San Francisco-based Flixster, which offers movie listings, reviews, quizzes, games and other activities and claims more than 20 million monthly users, did not disclose the financial terms of the deal.

It said IGN would receive a minority equity stake in Flixster, which was launched in early 2006.

"Rotten Tomatoes has built a fantastically well-known brand that moviegoers trust when making their decisions," Flixster president and chief operating officer Steve Polsky said in a statement.

"Combined with Flixster's social networking and word-of-mouth, we're creating the leading movie destination on the Internet," Polsky added.

Rotten Tomatoes aggregates reviews from hundreds of movie critics and rates them with its "Tomatometer."

Flixster, which offers movie applications for Facebook, MySpace, Bebo and other social networks and for mobile devices, said both its site and Rotten Tomatoes will continue to be available as separate properties.
