In 1973, a group of trade associations from the grocery industry formed the Uniform Product Code Council (UPCC) which, with the help of consultants Larry Russell and Tom Wilson of McKinsey & Company, defined the numerical format that formed the basis of the Uniform Product Code.[4] Technology firms including Charegon, IBM, Litton-Zellweger, Pitney Bowes-Alpex, Plessey-Anker, RCA, Scanner Inc., Singer, and Dymo Industries/Data General, put forward alternative proposals for symbol representations to the council.[citation needed] The Symbol Selection Committee finally chose to implement the IBM proposal designed by George J. Laurer in the North Carolina Research Triangle Park but with a slight modification to the font in the human readable area.[citation needed]
