European subscriptions to WSJ.com, which claims to be the biggest paid subscription news site in the world, number more than 16,500 - of which 6,300 are sold in the UK and Ireland. There are 18,500 subscribers throughout Europe, the Middle East and Africa.
WSJ.com now has a total of 664,000 subscribers, a rise on the 612,000 it had at the same time last year. About 35 per cent of these subscribers also take the print product.
A stand-alone online subscription costs $79 (£50); the online tariff for those who also take the print version is $39 (£25).
Neil Budde, publisher of WSJ.com, said: "Ad revenues are up 25 per cent year on year. There are some positive indications that people are stepping back into online advertising, but are now picking higher-quality sites to advertise on."
He was encouraged that the consumer electronic publishing (CEP) group within WSJ.com's parent, Dow Jones, posted an EBITDA profit in the third quarter.
"We expect WSJ.com to be profitable in the near-future," said Budde.
"But we won't put an exact time frame on it."
He added that WSJ.com had not seen any impact from FT.
com's decision to charge for content. He believed that it might help, as it made people more aware that they have to pay for online content.
In July, FT.com revealed it had 17,000 paying subscribers, half of whom are from outside the UK.
