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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.
NBCUniversal
In January 2006, NBC Universal launched a new cable channel, Sleuth. The channel's programming dedicated to mystery/crime genre. Sleuth Network's initial slogan was "Mystery. Crime. All The Time." In early 2008, the channel unveiled a new slogan, "Get Clued In." On August 15, 2011, Sleuth rebranded as Cloo, in order to be able to trademark and own the name, as NBCUniversal cannot so with the name Clue (as Hasbro owns the rights to it with their board game Clue). NBCUniversal also explained that another reason for the name change was the word "Sleuth" is too common for search engines (a Google search brings up over 9,530,000 results).
