NBC has used many corporate logo variations since 1926, when its radio network began transmitting programs across the country.

From 1926 to 1946, the graphics speak to the network’s identity as a radio station, showing a microphone “broadcasting” sound waves as little zipzag untis radiating outward.

Notable versions include the 1953 NBC keys, the 1954 12 color peacock, and the 1959 snake.

Other notable versions include the 1975 trapezoid N, the 1979 proud trapezoid N with peacock, and the 1986 6 color peacock.

The 1980s version of the NBC logo is still in use. Of late, its tail has seen additional treatments - gradients, glass-like transparency effects- to render it dimensional for HDTV.
