Popularity of the TV and automobile.
Throughout the U.S. the TV turned out to be widely popular, radio and movies survived. Radio turned to local programming of news, weather, music, and community issues. The post-World War II innovations such as microwave relays, which could transmit television waves over long distances, sent the television industry soaring.
In the U.S. the automobile rose from 6.7 million sales in 1950 to 7.9 million in 1955. The total number of private cars on the road jumped from 40 million in 1950 to over 60 million in 1960. The automobile industry rose this high because to an abundance of both imported and domestically produced petroleum leading to inexpensive, plentiful fuel for consumers.
