Twitter has topped 200m active users, more than doubling its audience since September last year.

While 2011 saw Twitter come to the fore in political events such as the Arab Spring protests and the UK scandal over superinjunctions, 2012 has seen it gain more mainstream attention through international events like the US presidential elections and the London Olympic games, as well as on-screen promotions of tweets and hashtags on TV news and talk shows, where its live, up-to-the-minute updates can really shine. Read more
