The Walt Disney Company became Hollywoods leader in the booming social game business by acquiring Playdom in a deal worth as much as $763.2 million. Playdom is one of a cluster of tech startups that make simple online games and sell virtual goods like a $2.50 outfit for a character in Playdoms Sorority Life,in which players shop,party and go to a spa. Such companies have grown by taking advantage of rapidly expanding social networks like Facebook. Disney will initially pay $563.2 million for Playdom,which is the No.3 social game company on Facebook with about 42 million monthly players. The deal includes $200 million in additional payments if Playdom achieves growth thresholds that were not made public. John Pleasants,Playdoms chief executive,will join Disney as an executive vice president and will report to Steve Wadsworth,president of the Disney Interactive Media Group. Pleasants,who impressed the Disney board with a presentation on social games at a recent company retreat,is expected to work to develop titles based on Disney characters and franchises. As social games becomes a more crowded and difficult field several hundred new games are introduced on Facebook weekly and most go nowhere brands that can be used as the basis for titles are becoming more important. When deciding how to place a bet we thought we should do it at a significant level and not just take a little shot, Disneys CEO,Robert A Iger,said in an interview.
