Twitter’s growth, both domestically and internationally has come as no surprise to users of the popular social network. What is surprising however, is how much more popular the social network is abroad. In the span of three short years, Twitter’s U.S. accounts have increased by 39 million users, but increased by a staggering 149 million users in the rest of the world.

Twitter popularity appears to have happened in tangent with the proliferation of mobile devices. Cell phones and Twitter have always gone hand in hand. A study was recently released that says there are almost as many mobile subscriptions as there are people on the planet.
