As his search engine inches toward irrelevance, besieged IAC CEO Barry Diller has found another crowded market to pour cash into: videogames. According to Variety, Diller plans to invest $50 million to $100 million of IAC's money on InstantAction, a new site from recently acquired IAC subsidiary GarageGames. GarageGames doesn't develop games quite so "casual" as the type Mark Pincus's Zynga produces, but the venture's product will still be Internet-based games made for those who don't want to waste time in front of a TV. Just like everyone else in the market, only a year or two later.
