The UK is Twitter's biggest market outside America, with 43 million US dollars (£27 million) in revenues in the nine months to the end of September, representing 40% of its overseas turnover, the company has revealed.
The figure, disclosed by the technology giant as it prepares to float on the New York Stock Exchange, is already more than 20 times higher than total annual overseas income three years ago, demonstrating the explosive growth of the company.
Twitter's turnover outside America was just 1.9 million US dollars (£1.2 million) in the whole of 2010, rising to 4.1 million US dollars (£2.6 million) in 2011 and 53 million US dollars (£33 million) in 2012.
The figures come as the San Francisco-based firm recorded a quarterly loss of 65 million dollars (£40.7 million) for the latest quarter, tripling from the same time last year, though revenues doubled to nearly 169 million (£105 million).
The company has swallowed losses of 483 million US dollars (£302 million) during its brief history as management focused on making the service more reliable and expanding its audience.
It ended September with 232 million active users, up from 218 in June, with more than three- quarters of the audience outside America.
However, much of this usage comes from less affluent countries which are less attractive to the advertisers that provide Twitter's revenue. It means the worldwide audience only supplies a quarter of the company's turnover.
But the UK contribution represented 10% of overall revenues of 422 million US dollars (£264 million) for the nine months to September. Twitter said no individual country from its overseas market contributed more than 10% of overall revenues in previous full years.
Overseas revenues for the period quadrupled year on year to 107 million US dollars (£67 million) while overall they doubled for the company as a whole.
