The first official tweet was sent out by creator Jack Dorsey who sent out a message that could rival Neil Armstrong’s moon-landing quote by saying, “just setting up my twttr.”
According to Twitter’s official blog, it has over 200 million users around the world with 400 million tweets being sent out on a daily basis. 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. Twitter released a video showing how the service has progressed throughout the years, with the hashtag and retweet features going live in 2007, Japan being added in 2008 and other milestones throughout its seven years of service.
The company was also giving its users the opportunity to celebrate today by tweeting out a message with the hashtag #Twitter7.
