Before any TV stations were on the air in the State of Iowa, radio station KRNT-AM - Des Moines, in cooperation with RCA and International Harvester, gave the 1946 Iowa State Fair visitors a preview of television. The demonstration was staged in the International Harvester tent. Closed circuit TV programs were produced using KRNT-AM personalities & Staff.
Bob Cannon, whose father was a KRNT engineer, supplied his fascinating picture story, to Des Moines Broadcasting.com website, which is believed to be Iowa's first exposure to television. Bob Cannon was a teenager at the time and worked as one of the camera men. Some of his presentation can be seen below.
