Bing + Yahoo search deal has finally signed on December 4, 2009

A press release published by Bing and Yahoo on Friday (Dec 4) shows both companies have officially signed the search license agreement.  Both companies announced to work together on July 29, and then, the deal was delayed few weeks as it passed the deadline on October 27.  From a very reliable source, we first thought the deal would be stamped at a public showing on Dec 2, as Bing top engineers picked San Francisco to show off their latest innovations including street maps, mobile apps, and some cool data.
