got milk?

  Got Milk? is an American advertising campaign encouraging the consumption of cow's milk, which was created by the advertising agency Goodby Silverstein & Partners for the California Milk Processor Board in 1993 and later licensed for use by milk processors and dairy farmers. It has been running since October 24, 1993. The campaign has been credited with greatly increasing milk sales in California though not nationwide.

Here is one of the campaign video. In the general sense, I think it's very very successful project. When I look this campaign , I feel the need of drinking milk!
