Yahoo has ceded its search operations to Microsoft under the aegis of Bing. This is either a brilliant move by Yahoo's new leadership or a major mistake from a floundering company, depending on who you ask. The interesting thing is, the day the deal was announced, Yahoo's market capitalization decreased by $2.9 billion while Microsoft's increased by the very same amount. That gives you some idea who investors thought won the deal. Still, time will tell and it can often pay to take the long view.
