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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.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
After losing on final appeal before the U.S. Supreme Court in May 1943, RCA sold Blue Network Company, Inc., for $8 million to the American Broadcasting System, a recently founded company owned by Life Savers magnate Edward J. Noble. After the sale was completed on October 12, 1943, Noble acquired the rights to the Blue Network name, leases on landlines, the New York studios, two-and-a-half radio stations (WJZ in Newark/New York City; KGO in San Francisco and WENR in Chicago, which shared a frequency with Prairie Farmer station WLS); contracts with actors; and agreements with around 60 affiliates. In turn, to comply with FCC radio station ownership limits of the time, Noble sold off his existing New York City radio station WMCA. Noble, who wanted a better name for the network, acquired the branding rights to the "American Broadcasting Company" name from George B. Storer in 1944. The Blue Network became ABC officially on June 15, 1945, after the sale was completed.
