Currently the Tiles program is a beta program being tested with some webmasters. Microsoft plans on announcing more details of the program at SMX West. A Microsoft spokesperson told us:

“We are always looking at new ways to improve the Bing user experience and today we began testing “Tiles”. A tile is an interactive logo or image displayed next to a search result that helps people easily identify a trusted site and make faster, more informed decisions. We are initially partnering with approximately forty-five content providers to test tiles focused on entertainment, local, travel and auto.”
