Back in the 19th century, inventors first began dreaming about devices to let people "see by electricity." An 1881 article in Nature speculated that transmitting images over distance was possible, but questioned whether is was worth "further expense and trouble."
In 1884, a German inventor created crude moving images by filtering light through a spinning disk punched with holes.. In the early 1920s, US and UK engineers sent still pictures and moving silhouettes using radio waves. In 1928, General Electric broadcast the first TV drama.
Picture quality steadily improved and audiences grew. The first widespread color telecast went out in 1954 and regular television broadcasts began in 1939. From 1945-1948 sales of TVs increased 500%. Today, there are televisions in some 110 million homes.
And Many of Them, Like Us, Have Many More Than One Set. --Cooter
