In 1983, the major manufacturers sold four sizes of ketchup: 14 oz., 24 oz., 32 oz., and
44 oz. Exhibit 3 shows industry volume mix by size over the previous 20 years. In 1964, only two
sizes had been available, and the 14 oz. size accounted for two-thirds of the volume. By 1983, over
80% of ketchup sales were in sizes that had not existed 20 years earlier.
