It is important to note that this figure is just registered users and not the "active user" number normally revealed by social networks.
Back in June, Twitter (who purchased the service seven months ago) said there were 13 million registered users. At the time, the app was only available on iOS and has since been released on Android.
Rival Facebook recently updated Instagram to have video-sharing capabilities, including 15-second clips compared to Vine's 6 seconds.
We've said this before and we'll say it again: this community - now more than 40 million of you - is amazing. Thank you for inspiring us.-- Vine (@vineapp) August 20, 2013
