11.2 Sound Broadcasting

Under the licences, sound broadcasting licensees were allowed to broadcast advertising materials not exceeding 12% of the broadcasting time. On the Cantonese channels, about 4% of the broadcasting time was used for advertising material (representing a 33% utilization rate), while the utilization on the English channels was much lower at 0.5% of the broadcasting time (4% utilization rate).
