Abstract :
Thank you, and good evening, ladies and gentlemen. You have had a long day, have participated in considerable good fellowship, have had a large meal, and, I suspect, are all ready to doze in front of your TV set. So, let´s tune in the show on channel 1980. The commercials are intriguing. For instance, the XYZ Electronic Service Company is plugging its complete inventory of replacement modules for home electronic appliances and its 24-hour centralized automatic sensing system. They guarantee to have replacement modules installed in any appliance the same day the original failed without your having to take any action-and in many cases without your knowing anything was ever wrong.
