By 1947, television sets (most with five and seven-inch screens) were selling almost as fast as they could be produced in cities which had television stations. Because of this, Major League teams began televising games and attracted a whole new audience into ballparks in the process. This was because people who had only casually followed baseball began going to the games in person and enjoying themselves. As a result, the following year, Major League attendance reached a record high of 21 million.
