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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.
NBC
In December 2005, NBC began its first week-long primetime game show event, "Deal or No Deal"; the series garnered high ratings, and returning as a weekly series in March 2006. Otherwise, the 2005–06 season was one of the worst for NBC in three decades, with only one fall series, the sitcom "My Name Is Earl", surviving for a second season; the sole remaining anchor of the "Must See TV" lineup, "Will & Grace" also saw its ratings decline. That season, NBC's ratings freefalled to fourth place, behind a resurgent ABC, Fox (which would eventually become the most-watched U.S. broadcast network in the 2007–08 season) and top-rated CBS (which led for much of the remainder of the decade). During this time, all of the networks faced audience erosion from increased competition by cable television, home video, video games and the Internet, with NBC being the hardest hit.
