In elemental ways, magazines have not really changed all that much in the past, say, 75 years or so. A striking cover image; some snappy cover lines; a number of articles, some long, some short; and all of the editorial “content,” whether words or photos, surrounded by ads — which, of course, along with subscriptions, help pay the bills and keep the issues coming, week after week, month after month. In other respects, though, the magazines of three-quarters of a century ago could not have been more different than today’s. For example: take a look at those ads that we just mentioned.
