Now more than 22 million per year. Most families have at least two sets. Average viewing more than four hours per day. Most time-consuming activity besides sleeping. Medium is the message.

Spend time with family, friends, reading, active sports, etc. More than 60 percent of Americans are overweight. Americans are passive rather than active. Content of programming. Aimed at biggest audience, so TV seldom reaches its potential.
