Kraft Singles is a processed cheese product manufactured and sold by Kraft Foods, introduced in 1949. One of the more famous ad campaigns involved the claim that each 3⁄4 ounce slice contained "five ounces of milk", which makes them taste better than imitation cheese slices made mostly with vegetable oil and water 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.
In the US, Kraft Singles is manufactured in regular, 2% Milk, and Fat Free. In Australia, a short-lived product called Vegemite Singles combined Kraft Singles and Vegemite.
In 2010, it became a sponsor of Disney On Ice.
