Dreyer's: Dreyer's Grand Ice Cream Holdings, Inc., a subsidiary of Nestlé, is a United States-based producer of ice cream and frozen yogurt founded in 1928 as Edy's Grand Ice Cream in Oakland, California by Joseph Edy and William Dreyer.  In 1947 the partnership was dissolved, and in 1953 William Dreyer Jr. took over and changed the name to Dreyer's Grand Ice Cream.  In 1963, Junior sold the company to his key officers -- Al Wolff who ran the factory, Bob Boone who ran distribution, and Ken Cook, who managed sales and served as president from 1963 to 1977.  Cook's vision was to provide American families with a truly premium ice cream they could enjoy at home.  In 1977, with sales of $6 million and an employee base of 75 people, Cook sold the company to T. Gary Rogers and W.F. "Rick" Cronk for $1 million.  In 1981 the company expanded and re-adopted the name "Edy's Grand Ice Cream" when marketing its product east of the Rocky Mountains, so as to not be confused with another company named Breyers (today owned by Unilever).  Hence they market under the Dreyer's name in the Western United States and Texas, and under the Edy's name in the Eastern and Midwestern United States.
