Instagram announced on September 9, Tuesday that it has reached 400 million monthly active users (MAU), who are posting images of people, dishes, and landscapes on the photo sharing service. In a blog post Facebook's social network reported that its users include European and Asian celebrities such as soccer players and pop stars, while over 40 billion pictures have been uploaded to its site since its October 2010 release.
The social media giant shared that over three-fourths of Instagram users live outside the United States. More than 50 percent of its latest 100 million members since December 2014 were from Europe and Asia.
Many non-U.S. celebrities have joined the photo-sharing service. They include soccer players David Beckham (United Kingdom) and Toni Kroos (Germany), pop band T.O.P. (South Korea), and TV hosts Raffi and Nagita (Indonesia).
In addition, over 80 million Instagram pictures are sent daily, which receive 3.5 billion Likes every day, according to Wired. A grand total over 40 billion images have been shared.
Instagram is beating Twitter's 316 million and Pinterest's 100 million MAUs. In addition, the Facebook-owned company is going through tough times as it looks for a permanent CEO.
Instagram's popularity has been boosted with some big events. It captured the first photo of Pluto's surface. The social network also launched new features including portrait and landscape formats, and Search and Explore functions.
The photo-sharing social network has added 100 million users since December 2014. It doubled its user base in 18 months, according to Mashable.
Twitter co-founder Evan Williams told Fortune he was apathetic about Instagram passing Twitter in active users. He said its photo-sharing service was based on "pretty pictures"
