Kraft Singles is a pasteurize cheese product manufactured and sold by Kraft Foods Inc, introduced in 1947. One of the more famous ad campaigns involved the claim that each slice contained "five ounces of milk" (with milk being poured into a glass next to Kraft Singles), which makes them taste better than imitation cheese slices made mostly with vegetable oil and water (with oil being poured into a glass next to imitation cheese with ominous music in the background) and hardly any milk. The campaign was lambasted for its implications that each slice contained the same amount of calcium as a five ounce glass of milk, which eventually led to a ruling in 1992 that ordered Kraft to stop making unsubstantiated claims in its advertising.
