Twitters 5th Birthday!
March 21, 2001 was the anniversary of Twitter. Jack Dorsey, the cofounder of twitter tweeted for the very first time. After five successful years Twitter has over 200 million users. The tweeters of Twitter include tech luminaries, celebrities, companies (including Evil Controllers!), the president of the United States, and of course people just like you and I.
In 2007 Twitter averaged 5,000 tweets per day, and now they average 140 million tweets per day, that is more than 1,600 every second. Two years later broadcast channels began to use twitter to report major news events.
