In January, a xylophone and mallet was shown with a three tone "G E C" tone. As seen in the video in the Video section.
In 1956, John J. Graham created the first NBC peacock logo. It featured 11 feathers. This logo had the first color ID. As shown in the videos.
The NBC Snake was usually featured at the end of each show. At the start of every show, the xylophone/peacock logo would be shown.
This is shown with or without the stylized "N".
In May 1986, NBC introduced a new version of the peacock logo. The number of feathers had been reduced to six, the head of the peacock was flipped and the stylized N was confined to history.
The firm behind the new logo was Chermayeff & Geismar. They also created a special font which was used for the letters underneath the peacock. The font was also used in special logos for NBC departments and stations.
