Happy birthday, Twitter!

Happy birthday, Twitter!

Today marks five years since Jack Dorsey, Twitter’s founder, sent the first tweet known to man. On March 21, 2006, @Jack sent the cryptic tweet: “inviting coworkers”.

Since then, by any measure of growth and engagement, Twitter has been growing at a record pace, and has become pretty much pervasive across businesses and consumer. Twitter has become a new channel for businesses to communicate with customers, a new way to handle customer service, and much more.

To celebrate its anniversary, Twitter released some numbers on the service:


  • Three years, two months and one day. The time it took from the first tweet to the billionth tweet.
  • One week. The time it now takes for users to send a billion tweets.
  • 50 million. The average number of tweets people sent per day, one year ago.
  • 140 million. The average number of tweets people sent per day, in the last month.
  • 177 million. Tweets sent on March 11, 2011.
  • 456. Tweets per second (TPS) when Michael Jackson died on June 25, 2009 (a record at that time).
  • 6,939. Current TPS record, set four seconds after midnight in Japan on New Year’s Day.

  • 572,000. Number of new accounts created on March 12, 2011.
  • 460,000. Average number of new accounts per day over the last month.
  • 182 per cent. Increase in number of mobile users over the past year.

  • 8. 29. 130. 350. 400. Number of Twitter employees in Jan 2008, Jan 2009, Jan 2010, Jan 2011 and today.
