People love to tweet about television shows they are watching; this much, we know. But now the analytics technologies are producing the payback: televsion advertisers will find out and tweet them back.

This new possibility comes thanks to Twitter having bought the MIT startup Bluefin labs (see “A Social Media Decoder”). Bluefin measures people’s reaction to specific airings of TV shows and ads, which it tracks and aligns with the tweets it captures. It also keeps track of what individual tweeters are talking about over time.

So don’t be surprised, next time you tweet about a great Super Bowl play, when the Doritos tweet you back. The plan was announced and explained here, in a Twitter blog written by the Bluefin cofounder Michael Fleischman, who is now a Twitter product manager for revenue.
