Electronic News Gathering.
A term used to describe a variety of television news reporting and also the professional video cameras which are used by the crew doing ENG.
ENG (compare to EFP) consists of recording incidents, interviews and b-roll footage and then returning to the studio for editing and broadcast. Most pre-prepared segments on television news consist of ENG material edited in the station. "Channel X investigates daycare|restaurants|insurance companies|auto mechanics" expose-everything reports are a good example of ENG work.
Accordingly, ENG cameras are designed with gathering in mind. They typically have on-board light and sound meters, white balancing, and a variety of audio inputs and status indicators plus a dock where various tape decks can be "mated" to the camera (for Beta, DV, etc.). These cameras do not have editing capabilities. Most video cameras in use by news crews nowadays are actually EFP.
