News Corp., the newspaper publisher controlled by Rupert Murdoch, agreed to buy the owner of Realtor.com for $950 million, expanding its digital real-estate listings to compete with sites such as Zillow.com.

Shareholders of the U.S. online real-estate business Move Inc. will get $21 a share in cash, New York-based News Corp. said today in a statement. That’s 37 percent more than Move’s closing price Monday, and the total purchase price is net of the target’s cash, the company said.
