Twitter App Maker UberMedia Buys Social News Site Mixx

UberMedia, which is behind Twitter clients like Echofon and Twidroyd, has purchased Digg-like news site Mixx. On Mixx, users post interesting stories, photos, or videos and vote and comment on those that others submit; it also lets publishers set up “channels” that aggregate social chatter related to a specific topic or brand. UberMedia says it will now use Mixx to add “channels” to its existing apps.

This is the latest of a series of acquisitions by UberMedia, which was previously known as TweetUp. In July, it purchased Android Twitter client Twidroid, as well as Popurls, which aggregates items from the New York Times (NYSE: NYT), Twitter, Digg and other sites. So far this year, it has purchased Twitter apps Echofon and UberTwitter.

Financial terms of this deal were not released. Mixx had raised more than $2 million from backers including the Los Angeles Times, which made a strategic investment in the company three years ago.
