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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.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
In 2000, NBC was caught in the dilemma of having to televise a first-round playoff game between the New York Yankees and Oakland Athletics over the first presidential debate between George W. Bush and Al Gore. NBC decided to give its local stations the option of carrying the debate or the baseball game. If an NBC affiliate decided to carry the debate, then the Pax TV affiliate in their local market could carry the game. NBC also placed a crawl at the bottom of the screen to inform viewers that they could see the debate on its sister channel MSNBC.
