TweetDeck, led by Iain Dodsworth, had previously been linked with a rumoured buy-out by UberMedia, which owns several third-party apps used to access Twitter.
A sale to Twitter would be the latest showdown in what appears to be a growing rivalry between UberMedia and Twitter itself. Twitter blocked several UberMedia apps in mid-February, and there have been reports that UberMedia is preparing to launch its own Twitter-like service soon.
Twitter has indicated that it wants to take more control over how users access Twitter — even going as far as telling third-party developers not to build Twitter clients — and by purchasing TweetDeck it would take control of the most popular third-party Twitter client.
The only more popular method used to access the microblog is the Twitter website, according to data collected by TwitStat. Third is Twitter for iPhone. That app was known as Tweetie, until Twitter purchased it last April. We’ve asked Twitter for comment and will update if we get any details.
