Instagram Hits 400 Million Monthly Users, Mostly Outside U.S.

  • Compares with Twitter's 316 million monthly active users
  • Brazil, Japan and Indonesia added the most new Instagrammers

Facebook Inc.’s Instagram has passed 400 million monthly active users, mostly by adding people in countries outside the U.S.

That compares with Twitter Inc.’s 316 million and Pinterest Inc.’s 100 million. Instagram’s number increased from the 300 million mark reached nine months ago, according to the company. Facebook has 1.49 billion monthly active users.

More than 75 percent of Instagram’s users live outside the U.S., with most of the new participants coming from Brazil, Japan and Indonesia, the company said. 

As it expands, the photo-sharing application has started to ramp up its advertising business, taking advantage of Facebook’s network of tools and marketers to increase its offerings and global reach. At the beginning of this month, Instagram advertised in eight countries. By the end, they’ll be making money in more than 200, the company has said.
