Cloud- based enterprise social networking software Yammer has been purchased by Microsoft for £768 million.

Yammer will be integrated into part of Microsoft’s Office Division and will be continued to be managed by its CEO David Sacks.

Yammer provides social network like capabilities such as those of Facebook and Twitter, adapted for use within the workplace. Larry Cannell, a Gartner analyst, commented on the deal: "This immediately makes Microsoft a stronger competitor in the enterprise social market,"
