The famous NBC Peacock logo was first hatched in 1956 as a still slide at the begining of each NBC color telecast. In 1957 a fully animated version was broadcast. The visual of the peacock unfolding his multi-colored feathers along with impressive orchestrated music and a very authoritive announcement "The following program is brought to you in living color on NBC." All designed to make black & white set owners feel like second rate boobs. An updated version, with new music, was introduced in 1962. Before the peacock, NBC used a still slide, colorized version of it's NBC chimes logo. The color chimes was first seen in late 1953 test color broadcasts. This logo can be seen on my web page in the CT-100 section.
