WNBC

Background
WNBC is one of the O&O's (owned and operated network, if you're confused) of the NBC television network and is also the flagship station of NBC. It is known for being the first TV station in America, first signing on at 1:30 pm on July 1, 1941, which was one full hour before WCBW (now WCBS).

WNBC's history traces back to the experimental station W2XBS, which was founded in 1928 by RCA, which was just two years after NBC was established as a radio network. It was originally a test bed for the RCA Photophone theater TV system, which was experimental at the time. This station does have a few firsts. These include, the first televised Broadway drama (June 1938), the first live news event covered by a mobile unit (November 1938), and the first of 3 sports (baseball & football in 1939, hockey in 1940).

Editor's Note: This isn't too creative, whatsoever. But at the same time, this is the 1930's, so we can't judge it too much.
