The postwar era brought a new product: The clock radio. This ad, from the June 1946 issue of Radio Retailing, showed one of the earliest examples from General Electric, which appears to be a model 50, a four-tube set.

With this new innovation, customers could say goodbye to sleep-shattering alarms, but after five minutes, an alarm would sound, to keep them from cheating.  Dealers were encouraged to stock up, since it was a natural for multiple set sales.  Everyone in the family would want one, and there was a great ad campaign in progress, along with full color point of sale displays.
