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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.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
In summer 1957, beginning with "Your Hit Parade," the peacock became animated and introduced every NBC color show until a revamped animation appeared in 1962. Its musical backing was a gong while the peacock began its formation, with a male announcer saying "The following program is brought to you in living color on NBC," while the music crescendoed followed by a nine-note flourish while the peacock's feathers changed color and finally spread out. According to Game Show Network executive David Schwartz, the first announcer who spoke those famous words behind the Peacock graphic logo was Ben Grauer, a familiar voice on NBC since 1930. A slide with the letters "NBC" in red, green, and blue respectively and with "TELEVISION" underneath appeared at the end of every color show.
