Microsoft and IBM, two of the world’s most established technology companies, have developers in Massachusetts building the companies’ own versions of one of the Internet’s newest giants: Facebook.
Both are creating social networks that companies could own and use within their offices, rather than have employees chatting with each other on the uncontrolled online landscape that Facebook has become.
The companies both have teams in Kendall Square in Cambridge - so close to each other that they are probably checking in at the same pizza spots on Foursquare.com.
And both sometimes refer to their projects as “creating a Facebook for business,’’ but they are more complicated than that. The companies are incorporating the features people expect on their favorite social networking sites - from the ability to post comments to “liking’’ projects to sharing documents and photos - in the complex suites of office software they sell to businesses.
