Radio and television have provided many of the common shared experiences in our lives. Even though we may have grown up and lived thousands of miles apart, we listened to and watched the same shows, knew the same actors and actresses, and could recite all the same commercials. These nostalgia-based legends, therefore, are equally familiar to all of us: we wonder what happened to those ephemerally ubiquitous actors and actresses once their shows finished their runs or their commercials were no longer in vogue, and we debate exactly what occurred on shows for which no tapes exist. So ingrained in our consciousness are some of these radio and television "memories" that we vividily recall events that never even took place . . .
