New Sydney/Melbourne radio station Vega has struggled to find an audience since it launched last year. Now comes news that one of its stars, Wendy Harmer, has quit. If the failure of the Vega format sounds like bad news for radio, the people who run our broadcast companies - and have paid many millions for their licences - better hope that Jeffrey Cole, the director of the centre for digital future at the University of Southern California, isn't on the money when he predicts the ultimate death of radio (and daily newspapers). He says the survivors among existing media in 50 years time will include music, cinema going, Sunday newspapers, and lifestyle and special interest magazines.
