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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.
Logo of NBC
In 1943, NBC introduced its third logo, a microphone surrounded by lightning bolts, which was a modification of the original 1926 logo used by the NBC radio network. Lightning bolts were also part of the logo of corporate parent RCA, as well as that of one-time sister company RKO Pictures. The waves placed on the left side were meant for the radio network, and the right waves were meant for the television network. A network identification featuring this logo includes a male announcer saying "This is NBC, the National Broadcasting Company", followed by the NBC chimes. On the network's flagship television station WNBT (now WNBC), this was accompanied by the same announcer saying "WNBT, New York". At the beginning of telecasts, a card was shown with a different NBC logo with the letters in cursive and enclosed in a rectangle (a logo also used at the end of broadcasts in the early 1950s). This was replaced by another card depicting an NBC cameraman operating an RCA camera was shown underneath the text "NBC Television Presents". The letters "NBC", lighting in tune with the chimes, indicated time for station identification or the end of a telecast.
