, introduced in 1949 . Kraft Singles is a pasteurized cheese product manufactured and sold by Kraft Foods, introduced in 1947. One of the more famous ad campaigns involved the claim that each ¾ ounce 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) 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 and also more calcium than imitation cheese slices, which eventually led to a ruling by the Federal Trade Commission in 1992 that ordered Kraft to stop making false claims in its advertising.

Kraft Singles are marketed under "pasteurized prepared cheese product".
