«(...) The marriage of automobile and radio seems so logical, one can only wonder why it took the intervention of entrepreneurs to make it happen. Happen it did; and nearly 80 years later, radio and the auto remain joined at the hip.
The seminal year was 1929. After failing twice in the storage battery business, Paul Galvin was encouraged to try to put a workable car radio into volume production, an idea that had pretty much been ignored by auto manufacturers.
(...) Choices on the listening side are changing as well, thanks to satellite radio and HD2 channels, which can deliver traffic reports and information focused on commuters and provide more options and useful data to drivers than ever imagined possible.
But no matter how high tech, the simple joy of a pleasant audio companion in the car, a pleasure that stimulated radio sales at their introduction 80 years ago, is still there.»
