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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.
Broadcast network
In 1941, the Federal Communication Commission's (FCC) "Report on Chain Broadcasting" reviewed the alleged monopolistic practices of the radio networks. The FCC was concerned NBC Red and NBC Blue were anti-competitive. Because the FCC did not have the power to directly regulate networks, it decided to enact regulations affecting the stations, and adopted standards intended to force NBC to relinquish one of its networks. In 1943, the Supreme Court upheld the FCC's power to enforce its chain broadcasting regulations. As a consequence, NBC Blue was sold to Edward Noble who later named it the American Broadcasting Company (ABC). After NBC Blue was divested the remaining NBC Red network was renamed the NBC Radio Network.
