Twitter wants to be your TV companion

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.

SnappyTV's technology is already used by a number of brands and media companies to post videos on Twitter (TWTR, Tech30), including news clips and sports highlights.

"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.
