EDITORIAL

Eighteen years ago there were a number of people engaged in floating television companies. They were annoyed when I denied that "television is just around the corner." Twelve years ago I ran into plenty of abuse when I returned from a world trip and reported adversely on television. Now again, to day, there is an element in the radio trade which is campaigning for television. I will again risk their displeasure by expressing my opinion that television in Australia is still well "around the corner," and that corner won’t be turned for a year or two yet. What is more to the point, I feel sure that when television does come it will not in any way displace the ordinary broadcasting as we know it now. It will not make present radio receivers obsolete or any less useful than they are today. The problems of television are not technical ones. Back in 1936 I saw several television demonstrations which left little to be desired. The big problems of television are practical ones, especially finance and the provision of sustained program es. It is easy enough to keep a radio station going all day when you have a big pile of records and a couple of big-mouthed announcers. It is much more difficult to arrange a full-time programme of television, not that it is required, as the looker-in gets a stiff neck after a few hours of intently watching a small screen in a semi-dark room. For the televising of the Melbourne Cup and that sort of thing a television service would be greatly appreciated, but is it worth millions? — A. G. HULL.
