In 1944 the Radio Manufacturers Association (RMA), and the National Electrical Manufacturers Association (NEMA) established the Joint Electron Tube Engineering Council (JETEC) to coordinate vacuum tube type numberings.
In 1958 JETEC included solid-state devices and develop standards for semiconductor devices and, changed the name to Joint Electron Device Engineering Council (JEDEC).
Later the Radio Manufacturers Association became the Electronic Industries Association (EIA) and JETEC became a subgroup of EIA.
