"I think in another 10 years in Australia, the only people who are going to be watching TV are those people over 60, and you're dead to the networks when you're 50." So says US academic Dr Jeffrey Cole. He's talking about the inevitable decline of traditional media. I think he's right on both counts - which is why Channel pushes its advertiser-friendly demographic line. Interestingly, though, commercial talk stations, which target older people, are extremely profitable. And, as I've said before, I expect to be far more cashed up and looking for things to buy when I'm in my fifties than I've been at any other time in my life.
