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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.
History of NBC Sports
By this time, NBC was mired in third place in the ratings, however sports remained a valuable television commodity for the network. In addition to the typically massive audience that watched the Super Bowl, NBC's broadcasts of the 1978 and 1980 World Series each earned a 32.8 rating, with the former being watched by an average of 44 million people and the latter by 42 million. This powerful sports lineup, coupled with a resurgent prime time schedule featuring hit shows like "The Cosby Show" and "Cheers", would put NBC back on top of the ratings by the middle of the decade. In December 1988, CBS obtained the exclusive broadcast rights to Major League Baseball, outbidding NBC and ABC and ending NBC's tenure as the home of baseball after 43 years.
