China Broadcast Corp, a Chinese provider of mobile multimedia broadcasting services, said it has built the world’s biggest mobile multimedia network, one that offers services to 500 million people, according to its technology and product director.

CBC, which was founded by the State Administration of Radio Film and Television in 2005, operates a national network that allows people to watch TV programs on various devices, including mobile phones, tablets and global positioning systems installed in vehicles.

By June, about 45 million people were subscribing to CBC services offered through China Mobile Multimedia Broadcasting, a homegrown mobile television and multimedia standard, said Wang Letian, technology and product director of CBC, in an interview with cctime.com on Monday.

Among them, about 21 million, or almost half, had paid for the services, Wang added.

By June 30, CBC’s mobile multimedia network was operating in 337 cities and 855 county-level cities, offering services to 500 million people in China. “We are proud to say that CBC is the world’s biggest provider of mobile multimedia services,” Wang told the website.

Zhang Haitao, deputy director-general of the State Administration of Radio Film and Television, said earlier this year at a Beijing conference that CBC seeks to be selling services to 100 million subscribers within three years.

The company is in talks with China Mobile Communications Corp about a possible investment from the latter.
