Twitter Celebrates Seventh Birthday

Today Twitter is celebrating its seventh birthday — the anniversary of Jack Dorsey’s first tweet — with a video recounting some highlights of Twitter’s history. On average, the service now has about 200 million active users, and sees more than 400 million tweets per day.

As we’ve grown, Twitter has become a true global town square — a public place to hear the latest news, exchange ideas and connect with people all in real time. This is where you come to connect with the world at large. Get on your soapbox to critique elected officials, or go sotto voce to the neighbor next to you. And as in other gathering places, commerce happens too (and jokes and art-making and debating, and — you get the idea).
