Twitter’s purchase of Cambridge-based social TV analytics startup and MIT Media Lab spinout Bluefin Labs has been confirmed by both companies. In a post on the company’s blog, Twitter says it will honor the company’s existing contracts but will not continue to offer its current products:

 This acquisition reflects our commitment to the social TV market, and builds on ourexclusive partnership with Nielsen announced in December to develop the Nielsen Twitter TV Rating, the centerpiece of social TV measurement based on Nielsen’s SocialGuide platform. We intend to honor existing Bluefin customer contracts, but we will not continue to sell Bluefin’s product suite beyond the existing contracts. We plan to collaborate closely with Nielsen and SocialGuide on product development and research to help brands, agencies, and networks fully understand the combined value of Twitter and TV.

So Twitter will presumably be putting the team to work on some new applications of social TV analytics, but it won’t go the route of just trying to monetize the company’s existing products.

Bluefin’s post offers a bit of support for the theory I wrote about earlier today as to why it wanted to sell, namely that it was overly dependent on Twitter for its data:

 While our products have always included data from multiple social media services, the reality is that Twitter is the platform where the overwhelming majority ­– about 95% – of public real-time engagement with TV happens. So we couldn’t be more excited to join Twitter.

Again, between this and Crashlytics, awesome news for the Boston scene. It seems likely that Twitter’s two biggest acquisitions in its history are currently from Boston.
