InteractiveCorp's real estate expedition

Media conglomerate a growing force online

Since Barry Diller’s InteractiveCorp bought LendingTree a year ago, the company has been on an acquisition binge, buying up high-traffic Web sites to add to its growing online real estate empire.

Diller purchased LendingTree in May 2003, then later acquired certain assets of GetSmart.com, the highly-coveted RealEstate.com domain and Domania.
