The world's first television stations first started appearing in America in the late 1920s and early 1930s. The first mechanical TV station was called W3XK and was created by Charles Francis Jenkins (one of the inventors of the mechanical television). That TV station aired its first broadcast on July 2, 1928.
According to Nielsen's forthcoming Advertising & Audiences Report, the average U.S. TV home now receives 189 TV channels—a record high and significant jump since 2008, when the average home received 129 channels. Despite this increase, however, consumers have consistently tuned in to an average of just 17 channels.
