EDITORIAL

The subject of television is still a sore one with the radio traders. Talk of television is having a devastating effect on radio sales. Yet a prominent radio concern recently made a wild publicity splurge on television, apparently just for some obscure political reason. The so-called "television" was actually the sending of an image over a line, and not true television. It was accompanied by the grossest exaggeration, and claims that it was the first television in Australia. With a complete disregard of truth in advertising, these claims were made by people who should have well remembered the similar "television" demonstrations which were given in Australia more than ten years ago One such demonstration was given by the W.I.A. boys at their exhibition in the Assembly Hall, Margaret Street, Sydney, in 1936. Television will come, eventually. It will cost a lot of money. It will be most disappointing from many angles. Special events will have their appeal, but long periods of peering into a small screen will give you a pain in the neck, in every sense of that expression. Television will never replace radio broadcasting as we know it to-day, or the cinema, either. It will not make present broadcast receivers obsolete. Most of our readers are recognised as authorities on radio matters by their many friends and business associates. I do hope that they will do their best to pacify the public and avert a television panic. — A. G. HULL.
