Twitter is extending its push into "social TV."
The company announced Thursday that it's buying SnappyTV, a San Francisco-based start-up that makes software for quick edits of live video and television into short clips.
"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," Baljeet Singh, Twitter's director of product management, said in a blog post.
SnappyTV said the deal would build on the companies' existing partnership, through which Web users "have been able to turn to Twitter to view highlights from major events from world championships to TV and awards shows to Presidential elections, just to name a few.'
The firms didn't disclose Twitter's purchase price.
The deal follows Twitter's acquisitions earlier this year of French start-up Mesagraph and the UK's SecondSync, both of which provide data on social media conversations about television. Twitter made a big push into video last year with the unveiling of Vine, an app for sharing short video clips.
But Twitter has struggled to maintain momentum in user growth lately. The company's stock is down nearly 40% this year, and chief operating officer Ali Rowghani resigned last week.
