Twitter is making big moves into the live streaming market, starting with Wimbledon last week.

But now they're moving away from pure sports coverage towards news as they will livestream CBS's coverage of this year's Democratic and Republican conventions in the US.

After making a big deal with the NFL to broadcast Thursday night American football games, it's unknown if Twitter is paying CBS to have the rights to rebroadcast the conventions. Final details of the stream are still being discussed by Twitter and CBS.

It's a big get for Twitter. Their whole reason to have live video is to have a Twitter feed right beside it, constantly churning over. It's hard to image many events this year that would have more people active on Twitter than the political conventions.

Twitter has said though that you won't need a Twitter account to watch the stream. That seems like a huge loss for Twitter, missing out on a lot of people who have no interest in Twitter but will tune in to watch.

The Wimbledon coverage was confirmed by Twitter to be a test for bigger projects later on. Perhaps this is what they had in mind. Or if they're looking at this as another test, then it'll get a big enough audience to see how Twitter can handle it.

The Republican National Convention takes place July 18-21 in Cleveland, and the Democratic National Convention is on July 25-28 in Philadelphia.
