The Penn Fruit Company was a regional grocery chain in the Philadelphia and Baltimore areas that operated from 1927 until 1979. During the firm's history it was regarded as one of the most innovative American supermarket chains. However, the company's innovations often were copied by its bigger rivals who eventually succeeded in causing the chain's demise.
