It took Twitter 3 years, 2 months, and 1 day to log its one billionth tweet. Now, Twitter users whip out 1 billion Tweets each week. We know this not because we counted them all, but because Twitter revealed these and other mind boggling stats in a blog post. To say that Twitter is growing at a record is an understatement.
A year ago, the average number of tweets sent out per day was 50 million. Today, that number is 140 million, with 177 million tweets floating through cyberspace on March 11, 2011. Major events obviously play a role in how many updates are sent each day. When Michael Jackson died, Twitter says it was processing 456 tweets per second (TPS). The current record is 6,939, which was set 4 seconds after midnight in Japan on New Year's Day.
Other numbers include 460,000, which was the average number of new accounts per day last month, and 400, which is how many employees work for Twitter. What the microblogging service didn't disclose, however, are revenue numbers. According to CNet , Twitter is valued at over $10 billion based on secondary-market trading.
