According to BusinessInsider, Cambridge based Bluefin Labs has been acquired by Twitter. Bluefin Labs is a spin out of the MIT Media Lab and has incredible technology that discovers and analyzes, in real-time, what people say via social media about the shows and ads that they’re watching on television. BusinessInsider is citing ‘sources,’ that claim this is Twitter’s largest acquisition to date – likely in the $50-$100 million range (or more). Social TV analytics – makes perfect sense for Twitter. See updates below.

Bluefin Labs was founded in 2008, but has been built upon deep machine learning principles developed over 15 years of MIT Media Lab research. The company has raised over $20 million in funding from Time Warner Investments, SoftBank Capital, Acadia Woods Partners, Bedrocket Media’s Brian Bedol, Jim Pallotta, Redpoint Ventures, Dan Gilbert, Lerer Ventures, Kepha Partners and the National Science Foundation.

This is Twitter’s second acquisition of a Cambridge based company in as many weeks. Just last week, Twitter acquired Crashlytics.

(UPDATING) Here is more on the acquisition from BusinessInsider, until we update.

UPDATE: We have reached out to Bluefin, Twitter & investors and are awaiting their confirmation.

UPDATE 2/5/13: Still waiting. BUT, Xconomy has apparently confirmed the acquisition and is pegging it around $100 million. Xconomy is also calling the Crashlytics acquisition at over $100 million – making that the largest Twitter acquisition. Now, I don’t remember the last time that Xconomy had a hard scoop like this, or the last time I cited them, but it is worth mentioning.
