Zillow, newspapers create ad network

Trulia forging similar ties with niche sites

Listings and valuation portal Zillow.com and a consortium of 11 newspaper publishers have forged an alliance allowing them to offer advertisers access to each other’s audiences.

The Zillow Advertising Network allows newspaper advertisers to reach Zillow’s national audience of more than 5 million unique visitors per month, the companies said, while Zillow advertisers get access to local audiences through real estate sections of newspaper Web sites.
