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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.

In April 2011, NBC Sports and Versus announced they had reached a ten-year extension to their television contract with the National Hockey League worth nearly $2 billion over the life of the contract. As part of the announcement, Dick Ebersol, the former chairman of NBC Sports, said that Versus would be renamed "within 90 days" in order to reflect the synergy resulting from the merger. However, the announcement of a new name did not come until August 1, 2011, when Comcast announced that Versus would be relaunched as the NBC Sports Network on January 1, 2012. The relaunch coincided with NBC's coverage of the NHL Winter Classic, which took place on the same day.
