Television Broadcasts Ltd (TVB) has appointed Prudence Chan Bik-wah as general manager of international operations with immediate effect, the company said on its website on Tuesday.

Hong Kong's dominant free-to-air broadcaster gave no further details.

Chan was formerly chief of the city's smart card payment system provider Octopus Holdings Ltd, a subsidiary of MTR Corp Ltd.

Earlier this year, a consortium led by local businessman Charles Chan bought control of TVB for about HK$6.26 billion ($806 million).
