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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.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
According to the New York Times, 9-2-88, p. A3, John J. Graham and Herb Lubalin of Sudler & Hennessey designed a peacock for the NBC television network: an abstraction of an eleven-feathered peacock indicating richness in color. This brightly hued peacock, which NBC called the "Bird," was adopted because of the increase in color programming. In addition, NBC's owner, RCA, manufactured color television sets. As a result, the peacock became a marketing tool, in the hopes that people tuning into NBC would purchase color TV sets. NBC's first color broadcasts showed only a still frame of the colorful peacock. Several modifications were made by NBC before the emblem made its first on-air appearance on May 22, 1956.
