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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.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 News
The original NBC Radio Network was purchased by Westwood One in 1987 as General Electric, which acquired NBC's parent company RCA, divested most properties not pertaining to the NBC television network. NBC Radio's news operation was merged into the Mutual Broadcasting System, then into Westwood One's then-corporate sibling CBS Radio, and eventually assimilated into the syndicator itself. Initially just a service limited to one-hour reports from 6 a.m. to 10 p.m. ET, on March 5, 2012, Dial Global – which had acquired Westwood One – announced NBC News Radio would expand to a full-time 24-hour radio news network, replacing CNN Radio (that itself replaced both NBC Radio and Mutual in 1999).
