<P> Mechanical televisions were commercially sold from 1928 to 1934 in the United Kingdom , United States , and Soviet Union . The earliest commercially made televisions were radios with the addition of a television device consisting of a neon tube behind a mechanically spinning disk with a spiral of apertures that produced a red postage - stamp size image , enlarged to twice that size by a magnifying glass . The Baird `` Televisor '' ( sold in 1930 -- 1933 in the UK ) is considered the first mass - produced television , selling about a thousand units . </P>
