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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.
Major League Baseball on NBC
From 1947 to 1956 and again in 1965, NBC only aired the All-Star Game (beginning in 1950) and World Series. From 1957 to 1989, the network aired the Saturday afternoon "Game of the Week" (or a variation of it prior to 1966, when NBC did not hold the exclusive over-the-air television rights). From 1994 to 1995, NBC aired games under a joint broadcasting venture with Major League Baseball and ABC called The Baseball Network. From 1996 to 2000, the network's league coverage was reduced to postseason games (three Division Series games in prime time, the American League Championship Series in even-numbered years, and the National League Championship Series and World Series in odd-numbered years), as well as the All-Star Game in even-numbered years (during years when NBC did not hold the rights to the World Series).
