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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.
NHL on NBC
On April 19, 2011, after ESPN, Turner Sports and Fox Sports placed bids, NBC Sports announced it had reached a ten-year extension to its television contract with the NHL (through the 2020–21 season) worth nearly $2 billion over the tenure of the contract. The contract would cover games on both NBC and sister cable channel Versus, which became part of the NBC Sports family as the result of Versus parent Comcast's controlling purchase of NBC Universal earlier in 2011. In relation to the contract's announcement, Versus would receive a new name to reflect its synergy with NBC Sports; the channel rebranded as NBC Sports Network on January 2, 2012 (it would later be abbreviated on-air and then officially shortened to NBCSN); NHL coverage on Versus would begin to be produced identically to NBC's NHL coverage beginning in the 2011–12 season, leading up to the brand change.
