The primary demand expansion program supported by the federal government through the Department of Agriculture is known as the commodity checkoff program. It is responsible for a series of advertising campaigns with aims to create higher demand for commodity products such as milk, beef, pork, and eggs. Familiar slogans from these campaigns include "Got Milk?"; "Pork. The Other White Meat"; and "The Incredible, Edible Egg". Checkoff programs do not exist for some of the healthier foods grown and produced in the U.S., including poultry, fish, and whole grains, and marketing support for produce is very minimal.
