Twitter to live-stream Republican & Democratic conventions

Twitter says it will live-stream CBS News' online coverage of the Republican and Democratic conventions later this month, a first for the social media outlet.

People will be able to watch video of the conventions on mobile devices and desktops alongside a feed of political tweets, the company said on Monday. The GOP convention begins in Cleveland on July 18, with the Democrats in Philadelphia the following week.

Besides being the latest example of Twitter's foray into video, the announcement is a major shot of exposure for CBSN, which is CBS News' two-year-old live online stream.
