Metro Broadcast Corporation has become the third digital radio station to go off-air, as it announced it would return its digital audio broadcasting licence to the government. The station said in a statement on Monday that the development of digital audio broadcasting had been unsatisfactory since it went into operation in 2012 and it had struggled to attract advertising revenue. It also complained about a lack of support, without giving details. The news came just a month after Digital Broadcast Corporation decided to hand back its licence. Phoneix URadio halted operations in September last year. Time for Hong Kong to scrap analogue radio and switch to digital, analyst says Secretary for Commerce and Economic Development Greg So Kam-leung said he was disappointed at the latest failure. “But we understand their decision.” So said the government was reviewing the development of digital audio broadcasting in the city and a report would be completed by the end of the year. He dismissed claims that the government had not done enough to develop digital radio. “Whether a new technology can develop is up to the market,” he said. Metro Broadcast’s three digital channels will operate normally until October 12. Two of the channels will be combined with its FM services, while the other will play music round the clock until authorities it to cease operating. Affected staff would be given other roles.
