PanARMENIAN.Net - Twitter has posted a video to commemorate seven years since Jack Dorsey made the first ever tweet, The Verge says.

The video features several crucial moments in the history of the service like the first use of retweets and hashtags, the first tweet from space, and a shout-out to new video service Vine.

Other moments include events that shook the world both on Twitter and beyond, such as the Japanese tsunami, the Tahrir Square protests in Egypt, and President Obama getting the most retweets ever upon his re-election.

In a blog post to accompany the video, Twitter notes the recent milestone of reaching 200 million active users — an increase of 60 million over the past year — and says that more than 400 million tweets are sent every day.
