Network Logos - The CBS logo, the "Eye," was designed by William Golden and introduced to television on September 10, 1951. The logo was judged in 1976 to be the most recognized trademark in the world. The logo for the NBC Television Network was a Peacock with 11 plumes in its multi-colored tail. It was designed to showcase regular color broadcasts introduced to television in the late 1950s and seen on such shows as BONANZA/NBC/1959-73, the first western to be televised in color. The Peacock logo was retired on December 31, 1975, replaced by a strange triangular design resembling the letter "N". It now has six plumes with the colors (left to right) yellow, orange, red, purple, blue, and green.  See also - BIRDS - "NBC Peacock"
