In recent times, it has grown in influence with it being available for the iPhone and Android platforms also. A previous report from TechCrunch also says that Twitter bought the company to keep away UberMedia from having too many Twitter-related clients in its portfolio. UberMedia has already bought UberTwitter, EchoFon and other Twitter-related startups. Having TweetDeck too in its portfolio would let it have too much leverage over Twitter.
Sensing this, Twitter made a counter offer to TweetDeck and secured it from getting gobbled by UberMedia. An official announcement is expected in two days' time.
