In a very nonchalant tweet Tuesday, Vine announced that it has now surpassed 40 million users.
How much growth is that? A whopping 207% since it hit 13 million just two months ago.
Though Vine has only been around since January, it has quickly become a leader in the short-video market, and a big reason for that is its users, whom are passionate about making six-second videos with the iPhone and Android app.
Vine has had to compete with rivals that came before it -- such as Viddy, Kik and Tout -- and Instagram, which added video as a feature in June, but the Twitter-video service separated itself from the crowd by quickly finding its niche: comedy.
Not long after launching, some Vine users quickly gained thousands of followers thanks to hilarious clips they were posting. With just six seconds, users have a short time to deliver a quick punch line, and many Vine users have perfected this craft. Their videos become extra funny thanks to Vine's loop feature, which will play a video over and over again until a user stops it or moves on to another Vine.
