Twitter said on Thursday it has bought SnappyTV, a California firm that lets people edit and share clips from TV broadcasts.
Terms of the deal were not disclosed.
SnappyTV, launched in 2010, has been collaborating with Twitter to "inject the best video content into Twitter's real-time conversation, straight from the TV to your mobile device," Twitter said on its official blog.
Twitter added: "While we continue to invest in SnappyTV's product and integrate it more tightly with Twitter, we also plan to maintain our partners' ability to post high-quality videos to other platforms."
"As Twitter has grown as the companion to live events and broadcast media, SnappyTV will help partners and brands bring the best videos into the conversation, when it matters most," Twitter added.
Since the beginning of the year Twitter has been on a shopping spree, in particular for TV audience rating firms or social media advertising companies. These include the US firm Gnip, Mesagraph of France and Britain's SecondSync.
