Vine reaches 40 million users in just 7 months

Reaching 40 million users is impressive for a seven-month-old app.

Vine, which was acquired by Twitter almost a year ago, has hit 40 million users. The company announced this milestone via a tweet earlier.

Vine launched in January this year, but the app (which allows you to make six second videos) has genuinely emerged as a new kind of video art form and has even created its own set of Vine video stars.

Reaching 40 million users is impressive for a seven-month-old app, but a couple of caveats: First, the number of registered users isn’t necessarily a sign of sustained engagement. Anyone can sign up for an app once and never use it again.
