The social media network has already started to embrace video with its Amplify programme, which allows sponsored video excerpts of televised content to be easily viewed on mobile.
In a statement, Twitter said: "One of the best ways to follow events as they unfold is through real-time videos on Twitter.
"As we continue to invest in video, it’s important for us to provide tools that make it easy for TV broadcasters, businesses, and event producers to share high-quality videos. To that end, we’ve agreed to acquire SnappyTV."
This is just the latest video expansion from Twitter after it bought video sharing app Vine, which allows users to send each other six-second video messages.
