A characteristic proffered by the golden days of radio was the harmonious relationship—a venerated respect, possibly—that existed between advertisers and their representatives in the ethereal age. For the client and the practitioner, it very likely was the best of both worlds.

One of my professors once said, as long as you are around other people, advertising is unavoidable.
