BackType, an analytics company focused around tweets, announced via its blog today that it has been acquired by Twitter. BackType's team and technology will be making the trip over to Twitter's offices where their "focus will be developing tools for Twitter’s publisher partners."

Our team’s relocating to the Twitter office. We’re very excited to not only join an amazing company that’s changing the world, but to continue building products in pursuit of our shared vision with Twitter.

BackType developed a product called "BackTweets," which allows content publishers to see who is reading their tweets and how "tweets convert to web traffic." As a result of the deal, BackTweets will be offered for free to current users and new user registrations will begin to slow down in the future. In addition, BackType services and API's will be discontinued. 

No further information about the deal was revealed at this time.
