Whiteboard
Albert Stallion invented whiteboards while working at Alliance in the 1960s. Alliance (now known as PolyVision) produced enameled steel for architectural cladding, but Stallion noted it could also potentially be used as a writing surface. Stallion later left Alliance to form his own whiteboard production company, MagiBoards.
NOMA (company)
When the NOMA Electric Company was located in New York City, it may have produced the first commercial printed circuit board in 1946 with its Party Quiz Game. It was an electrical board game with replaceable question cards and two electrodes which, when placed in the proper positions to answer a question correctly, cause a bulb to light. Initially hard-wired, the game was made thinner by hot pressing aluminum foil onto cardboard, with the electrical contacts made into the board.
