In the late 1950's and early 1960's, when color television was making its way into the marketplace, the "Big 3 of Networks" (NBC, ABC, and CBS) were looking for innovative ways to let the viewers know when a particular show would be broadcast in color. Thanks to a visit to the Greater Los Angeles Zoo, anyone old enough to remember these "In Color ID's" will tell you that NBC had the most memorable of the three. But don't take my word for it...See for yourself:
