Twitter has 200 million users! Twitter has 100 million users!

John Moe Sep 9, 2011

Both are kind of correct. Twitter, which has been historically stingy about sharing statistics, said in a blog post yesterday that the service has 200 million registered accounts and 100 million active users, active being defined by people who log in once a month at least. Of those 50 million log in every day. Some more math: 40% of the active users are passive once they get on the site. They read, they don’t tweet. Also: Each of the 50 top-rated Nielsen TV shows has a Twitter account, as do 87 percent of top Billboard-rated artists. Two-thirds of the NBA are active on Twitter, and every team in the NFL, MLB, NBA, NHL and MLS has an account.
