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.

Logo of NBC
The National Broadcasting Company (NBC) has used several corporate logos over the course of its history. The first logo was used in 1926 when the radio network began operations. Its most famous logo, the peacock, was first used in 1956 to highlight the network's color programming. While it has been in use in one form or another for all but four years since then, the peacock did not become part of NBC's main logo until 1979 and did not become the network's sole logo until 1986. The logos were designed by NBC itself. The first logo incorporated design from parent company RCA, and was a unique logo not related to the NBC radio network.
