Back in March 2016, you might remember Facebook announcing that three million businesses actively advertise on its social network. Well, now that number is four million. That’s one million advertisers added in less than seven months.
For comparison, Facebook’s main current rival in the social advertising space, Twitter, claimed more than 130,000 advertisers in the fourth quarter of 2015 (Facebook’s real main rival, Google, no longer says how many advertisers it has). And Facebook-owned Instagram announced last week that more than 500,000 brands buy its ads each month, up from 200,000-plus in February 2016.
