Invites users to showcase their 'creativity' in six-seconds or less.
Twitter has become increasingly mobile over the past year, launching Instagram-inspired photo filters for its Android and iOS apps, while expanding its Promoted Tweets mobile ads vertical.
The mini-blog has now acquired Vine, a mobile video service that allows users to record up to six-seconds of looping footage, similar to the way Twitter restricts its users to posts of just 140 characters.
Dom Hofmann, co-founder & GM, Vine, said: "With Vine, capturing life in motion is fun and easy. Posts on Vine are about abbreviation — the shortened form of something larger. They're little windows into the people, settings, ideas and objects that make up your life. They're quirky, and we think that's part of what makes them so special.
"We're also happy to share the news that Vine has been acquired by Twitter. Our companies share similar values and goals; like Twitter, we want to make it easier for people to come together to share and discover what's happening in the world."
You don't need to use Twitter to access Vine, but 'signing up is quicker if you do'. The app is only available for iOS at launch, but the firms are currently working on new platforms.
