Most people who are not ham radio operators are completely surprised when you tell them that there are amateur radio television stations. People do not know how much the amateur radio community has added to the advancement of the art of radio.
On July 2, 1928 the FCC authorized C. F. Jenkins W3XK in Wheaton, Maryland to broadcast the first television signals. For the first eighteen months these were only silhouette images from motion picture films but it was a start.
W2XB started broadcasting the first regular schedule television transmissions on July 21, 1931. W6XAO in Los Angeles went on the air on December 1931 transmitting images every day except Sundays and holidays. W6XAO continued the broadcasting for several years.
While commercial broadcasters saw the potential in broadcasting radio programs on the AM bands it was not until after World War II that commercial television really began to catch on.
The average person not acquainted with the amateur community does not know this because we, as hams, do not tell them. It is interesting that for so many years they have complained about hams interfering with their television programs and had not been for the efforts of some ham radio operators it is possible that they would not have television programs to watch.
