EDITORIAL
You may wonder why the Women's Weekly can give you so much reading matter for 3d. when I only offer you a much smaller publication for four times the price. There are many strange things in the publishing business. For example, when you pay your 1/- the actual amount received by the publisher will not nearly pay the printer's bill. The more copies the publisher sells the more money he loses, unless he can convince enough advertisers to support him. If I sold an extra 5,000 copies of Radio World each month I would be running at a dead loss. Silly, isn’t it? Paper, printing and block costs are up about double what they were in 1939, so are the prices of books, shoes, suits, motor cars and many other things. Yet there seems to be an unwritten law that the price of magazines must remain at not more than 1/- per copy. Getting back to the value offered by the Women's Weekly and other such publications; the explanation lies in the advertising revenue. With cosmetics, patent medicines and many house hold lines it becomes possible for the trades concerned to support general magazines with thousands of pounds' worth of advertising for each issue. But when it comes to technical radio only; well, the component manufacturers are having a pretty thin time of it and they cannot afford to spend big sums on advertising. So the publisher of a magazine devoted exclusively to technical radio can only shrink his publication to conform with the shrinking of the purchasing power of the shilling, if he wants to remain in business. Which makes it hard to explain why optomists should be wanting to start up in the publishing game. What is that they say about rushing in where angels fear to tread? Or is it that one is born every minute! — A. G. HULL.
