Why is there no channel one on television?
ANS: What is now WNBC in New York was licensed for channel 1 (50-56 MHz) from July 1, 1941 to September 30, 1946 when they were granted a modification of license for a change to operate on channel 4 (66-72 MHz).
As proof: the RCA model 630 television set included a 'Channel 1' position on its step tuner. WNBC may have been the only station to have operated on channel 1. Channel 1 was shifted to 44-50 MHz in June 1945, where it started to encroach on the frequencies assigned the infant FM broadcast band.
When RCA's David Sarnoff had FM reallocated after WWII (to kill it), the FCC issued a NPRM in May 1948 to use Channel 1 for other services. There was also TV in the 2.5 MHz region (the Charles F. Jenkins system, also killed by Sarnoff), as well as some other assignments for TV before WW II.
