Twitter Sees 600 Tweets-Per-Second #OMG #YeahButWheres TheBusinessModel

In 2007, Twitter broadcast about 5,000 tweets per day. Just three years later, it is broadcasting some 50 million–about 600 tweets per second. (Click chart above to enlarge.)

In a TPS report filed today (TPS here referring to “tweets per second” and not “Test Program Set” from the movie “Office Space.” Ha ha, what a funny coincidence.) Kevin Weil of the Twitter analytics team points out that tweets grew 1,400 percent last year. He also notes that the 50-million-tweets-per-day figure does not include posts generated by accounts that have been identified as sources of spam.

Further evidence that the microblogging service has pushed through the growth ceiling it hit last fall. As I noted last week, the latest metrics from comScore (SCOR), show Twitter.com with 73.5 million unique visitors in January, up eight percent from the 65.2 million who visited in December 2009.
