Emphasis Preaching Journal

Televisions today are all solid state. They don't have any tubes, except the picture tube. There are already ads out for the new flat-screen televisions and someday there won't even be picture tubes. Even ten years ago, a television store would sometimes take an old vacuum tube set as a trade-in. Their ads always said, "With working, solid state trade-in," but the businessman always tried to be agreeable, and when a customer insisted, he took the tube set in trade and let the customer think he had swindled the salesman.
