Topco was founded in the 1940's by a group of small, local grocery chains, independently owned and operated, that desired to cooperate to obtain high quality merchandise under private labels in order to compete more effectively with larger national and regional chains. 3 With a line of canned, dairy, and other products, the association began. It added frozen foods in 1950, fresh produce in 1958, more general merchandise equipment and supplies in 1960, and a branded bacon and carcass beef selection program in 1966. By 1964, Topco's members had combined retail sales of more than $2 billion; by 1967, their sales totaled more than.$2.3 billion, a figure exceeded by only three national grocery chains. 4
