Twitter has bought two Social TV firms, Bristol-based SecondSync, and French company Mesagraph, as it looks to cement the already-strong relationship between watching TV and commenting on it via Twitter.

SecondSync announced a deal to provide analytics around social media interaction with TV to Facebook in January. A month later, it released its first report, which revealed that 80 per cent of the conversations analysed by SecondSync across the US, UK and Australia took place on mobile.

The acquisition by Twitter will no doubt put at end to that relationship, and perhaps have Mark Zuckerberg get in there first. I suppose when you’re buying so many companies you can be forgiven for missing the odd one…

In a post on the SecondSync website, the unnamed author says: “Twitter is the only place that hosts a real-time, public conversation about TV at scale. By joining Twitter, we will be able to help take that experience, in concert with the rest of the TV ecosystem, to the next level – particularly in markets outside the United States.”
