WNBC-TV originally signed on as WNBT-TV Channel 1 on July 1, 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 NBC Televison.
In 1954 WNBT became WRCA-TV. The call letters WRCA meant Radio Corporation of America.
These logos were shared with sister stations KNBC in Los Angeles and WRC-TV in Washington, D.C.
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.
While the same 1980 "4" logo was kept by WNBC, NBC updated its peacock on May 12, 1986.
This logo's "4" has been used by the station itself and WRC-TV ever since. The same "4" was used on sister stations WTVJ in Miami–Fort Lauderdale, NBC's West Coast flagship station KNBC in Los Angeles and former NBC-owned station KCNC-TV in Denver; the two stations ceased using it in 1995 (when WTVJ switched its channel position with WCIX (now known as WFOR-TV), 1998 and 2003, respectively. The "-TV" suffix was omitted after NBC sold its AM radio station of the same callsign (now WFAN) in 1988.
The template has been used by the rest of NBC O&O stations up until 1995.
This logo also served as a template and was used for some of NBC's owned and operated television stations and for MSNBC.
The West Coast sister station KNBC in Los Angeles used it a year earlier.
