JF Ptak Science Books Post 1632
The first broadcast images in the history of television transmission were revolutionary if not very interesting. Beginning in 19028 the first experimental Radio Corporation of America (RCA, via the National Broadcasting Company, NBC, its broadcasting division) images were of Felix the Cat, and something that would be received with 60-line clarity on a two-inch display. For the most part, the daily two-hour broadcasts consisted of Felix or test patterns, broadcast from NYC, until 1931.
Image quality increased markedly by the 1932 field trials with the use of iconoscope cameras, which allowed for 240-line reception though still with very noticeable flickering. The 1934 trials were improved further to 343 lines and with some less amount of flicker.
