The ad network its cobbling together has prompted some industry observers to compare it to what Microsoft (NSDQ: MSFT) has done with its internet properties. That, in turn, has led to the inevitable speculation that the Redmond software giant could be looking at IAC as a potential acquisition target, though IAC has declined to touch that one.
