EBay Inc. executives said Thursday the company’s Internet-based phone service, known as Skype, has seen explosive growth in China and that the country is now one of Skype’s biggest market.
Speaking to hundreds of analysts and investors gathered at eBay’s San Jose, Calif., headquarters, Skype president and former eBay chief financial officer Rajiv Dutta said the service has 13 million users in China.
That’s nearly as many users as Skype has in the U.S., Germany and the U.K. combined, according to Dutta. The service has 6 million U.S. users, 3 million in the U.K. and 5 million in Germany.
