WNBC-TV originally signed on as WNBT-TV on July 1st, 1941. WNBT was officially the first tv station in the United States, although they and WCBW (Now WCBS-TV), were supposed to sign on at the same time. WCBW was delayed by one hour by technical issues. The WNBT call letters meant NBCTelevison
In 1954 WNBT became WRCA. The call letters WRCA meant Radio Corperation of America
Test pattern from this era. Was reused when WNBC shut off their analog transmitter after two weeks of Nightlight on June 26th 2009
Briefly in 1980, this logo was preceded by an "Octagon 4" and a "zig-zag" 4 that looked somewhat like a cross between the 4 seen here and the logo used by Pittsburgh, Pennsylvania ABC affiliate WTAE-TV.
This logo also served as a template and was used for some of NBC's owned and operated television stations and for MSNBC.
