How many tweets were posted per day on Twitter in 2012?

Twitter reported about 340 million tweets per day in March 2012. The figure was announced on March 21, when Twitter marked its sixth anniversary and said it had 140 million active users. At that point, the platform’s daily message volume had more than doubled from the roughly 140 million tweets per day reported a year earlier.

The number describes a particular point in Twitter’s rapid growth, not a fixed total for the entire calendar year. By June 2012, Twitter CEO Dick Costolo said the service was seeing more than 400 million tweets per day, showing how quickly activity was accelerating. Later historical summaries sometimes quote 340 million as the notable 2012 benchmark because it was the company’s widely reported March figure.

This statistic is also easy to confuse with user counts. The same March announcement paired 340 million daily tweets with 140 million active users. It did not mean 340 million people tweeted each day; the total included multiple posts from many users and automated or organizational accounts.
