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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.
NBC Radio Network
Many NBC radio stars gravitated to television as it became more popular in the 1950s. Toscanini made his ten television appearances on NBC between 1948 and 1952. In 1950, the radio network sanctioned "The Big Show", a 90-minute variety program that harked back to radio's earliest musical variety style but with sophisticated comedy and drama and featuring stage legend Tallulah Bankhead as its host. It aimed to keep classic radio alive as television matured and to challenge CBS's Sunday night lineup—much of which had jumped there from NBC in the late 1940s, including (and especially) Jack Benny. But "The Big Show"s initial success didn't last despite critics' praises; the show endured only two years, with NBC said to lose a million dollars on the project.
