| A very brief sign-off of Seattle's long-time ABC Network affiliate, running only about thirty seconds in length. Just a shot of the Seattle skyline at night, then several seconds of black before the transmitter is cut off. Though KOMO-TV came on the air initially in December 1953, the AM radio station that spawned Channel 4 did some experimenting with TV some 25 years before. On June 3, 1929, KOMO radio engineer Francis J. Brott televised images of a heart, a diamond, a question mark, letters, and numbers over electrical lines to small sets with one-inch screens. A handful of viewers were captivated by the broadcast. The Webmaster assumes that a mechanical "Nipkow disk" scanning system was employed in this experiment. |
