Zillow is an online real estate database that was founded in 2005 by Rich Barton and Lloyd Frink, former Microsoft executives and founders of Microsoft spin-off Expedia. Zillow has stated that it is a media company that generates revenue by selling advertising on the Web site.[2] In April 2009, Zillow announced a partnership to lend its real estate search engine to the Web sites of more than 180 United States newspapers as a part of the Zillow Newspaper Consortium. Zillow shares advertising revenue from the co-branded sites with the newspapers and extends its reach into local markets.[3]
