When television was first introduced into American society thirty years ago, writers and social scientists thought that this new invention would better American life. Television is going to bring American families closer together, predicted psychologist Joel Gold in 1949. Pictures which advertised television in the 1950s invariably showed a happy family gathered together in the living room, sharing the TV viewing experience. Who could have guessed that a quarter of a century later Mother would be in the kitchen watching a daytime drama, Dad would be in the living room watching a ball game, and the children would be watching cartoons in their bedroom?
