Micro-blogging site Twitter gained around seven million new visitors in June this year, attracting 44.5 million unique visitors globally during the course of the month, according to market research firm comScore.
ComScore's figures represent a 19 per cent increase on May 2009 and a 1,460 per cent inflation year-on-year and means that Twitter is the 52nd largest site in the world - just behind the BBC.
The research also revealed that the audience for Twitter is now 55 per cent international, with 20 million of its visitors coming from the US.
Last month, comScore revealed that of the 36.9 million people in the UK aged 15-plus who used the internet at home or at work in May, 29.4 million visited at least one social networking site.
