Driscoll's was officially founded in 1904, known at the time as Banner Berry Farm's Brand. They secretly kept Loftus as their supplier and also planted the Banner variety of berries exclusively. The company was the sole supplier of the Banner variety until Reiter formed an outside partnership in 1916 to market the Banner Berry plant. After twenty-years in business, the Banner variety was infected by the spread of a viral infection and Driscoll's began breeding and releasing new varieties of berries. The new varieties were developed by Harold Thomas and Earl Goldsmith from the University of California, Berkeley.
