The big guns on Instagram have seen their number of followers spike tremendously since the startup exited its iPhone-only stage and released its much-anticipated Android app on April 3.
Up until that point, Instagram had been downloaded 27 million times and only two users had more than 1 million followers -- pop stars Justin Bieber and Selena Gomez.
Days later, Facebook bought the photo-sharing app for $1 billion, attracting massive attention to Instagram.
Instagram now approaches 50 million downloads, and three more users are in the 1-million-followers club.
