IAC, with its stock share up 25% this year, has dozens
of Web properties from a variety of e-business sectors, including retail (Ticketmaster.com), financial services (LendingTree.com), search (Citysearch.com and Ask.com) and online dating (Match.com).
Its secret is pooling revenue from a bunch of different business that remain separate, which contrasts sharply with the integrate-everything approach used by Yahoo and AOL.
Barry Diller, the CEO of Web conglomerate IAC/InterActiveCorp., says the company's next move is to introduce a product that takes advantage of the migration of eyeballs from print to Internet-an under-exploited phenomenon that he says has a long way to go.
