Merger talks between Microsoft and Yahoo have reportedly broken down and are more likely lead to a cooperative effort of sorts, according to recent media reports.

The New York Post reported early on Friday that Microsoft had stepped up its efforts to buy Yahoo in an effort to fend off a common competitor, Web search leader Google . The Post said that Microsoft made the bid a few months ago; though Yahoo reportedly spurned the advances, the paper said discussions were continuing.
