NBC suit
An NBC (nuclear, biological, chemical) suit, also called a chemsuit or chem suit or chemical suit is a type of military personal protective equipment. NBC suits are designed to provide protection against direct contact with and contamination by radioactive, biological or chemical substances, and provides protection from contamination with radioactive materials and some types of radiation, depending on the design. It is generally designed to be worn for extended periods to allow the wearer to fight (or generally function) while under threat of or under actual nuclear, biological, or chemical attack. The civilian equivalent is the Hazmat suit. The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.
Logo of NBC
Starting in late 1959, an animated logo joined the Peacock, appearing at the end of every show. Starting with the "N", each letter would grow from the other, forming a stacked typographic logo ending with the "C", forming the base. This would be known as the "NBC snake". Several versions of this exist; the first is the snake forming in front of a multicolored background while a camera passed by with a jazz rendition of the NBC chimes, while the second consists of the snake forming against a color-changing background, going from blue to green to red, on each note of the regular, automated NBC chimes. The logo was also designed by John J. Graham.
In 1962, on "Laramie", a new version of the Peacock opening logo was introduced in which the bird fanned its bright plumage against a kaleidoscopic color background (with the eleven melded feathers shrinking and separating into the peacock's form). As with the 1956 Peacock, this logo appeared at the start of every NBC color program; as all NBC shows eventually began airing in color, it was generally used only to open those shows that were produced by NBC itself, such as "The Tonight Show Starring Johnny Carson". It was, however, seen on the NBC airings of "The Wizard of Oz" as well as on the broadcast of "Peter Pan", which had been videotaped at NBC Studios (NBC had previously telecast live versions of "Peter Pan" in 1955 and 1956 on the anthology "Producers' Showcase"). The "Laramie Peacock", named for the series which introduced it, used the same "living color" tagline as the first peacock, but the accompanying music was a soft, woodwind-based number; Mel Brandt provided the voiceover. It was revised further in April 1968; the music was slightly rearranged and the animation shortened by a few seconds, Another version, with Vic Roby announcing, "Now, a special program in living color on NBC", was unveiled for use on specials during this same period. It was shortened further in 1975, when the peacock was retired.
