The real-time information network is on pace to make about $140 million this year (a 210% leap from 2010) and then $260 million next year, an 86% jump. In 2013, Twitter could generate up to $400 million.
The microblogging platform has been slow to monetize but a sustainable business model is finally materializing. However, it is far from globalizing: the report suggests that Twitter will rely on 96% of its revenue this year coming from the U.S. and will still depend on America for as much as 88% of its revenue in 2013.
Twitter has over 200 million users, about half of which are considered "active."
