The “Radio Drama of Commercial Radio Hong Kong” carries 17 episodes of radio dramas (called "dramatized fiction" at the time) produced by the Hong Kong Commercial Broadcasting Co. Ltd. (Commercial Radio). They are excerpts from 10 serials including Folktale Mysteries, Ancient and Modern Eccentric Tales, Moral Fiction and Literary Fiction as well as from 6 sets of Stage Play Appreciation adapted for radio by drama clubs and aired on Commercial Radio's Cantonese channel during the period 1966-1976. Dramatized fiction had been the major program type on radio in the 1960s through the 1970s and those soundtracks are at present the only existing complete set kept by Commercial Radio. Restoration work was first carried out by the School of Journalism and Communication, The Chinese University of Hong Kong, where the soundtracks were transformed from magnetic tape to the computer format followed by noise reduction, tuning, and stereo effect production done by audio mixer and finally remastered at 10dBFS to get a 24bit, 48hz file format output. The soundtracks are donated by Commercial Radio. The project is sponsored by the Lord Wilson Heritage Trust with the organization and restoration works of soundtracks taken up by Dr. WONG Pui Fung. This collection not only marks the broadcast history of Commercial Radio but it also serves to entertain listeners from all walks of life. It remains our wish that more radio dramas will be initiated and more research works on them are produced in the future.
