It is sold in the United States, Canada and other countries. Its bright orange colouring is aided by the addition of annatto.
It is now the standard cheese used on a Philadelphia Cheese Steak sandwich.
A 1 pound (450 g) jar = 1 ⅓ cups

Cheez Whiz was invented in 1951 by Kraft lab technicians charged with creating a processed cheese product that would melt easily, without breaking down into oils. It was launched in 1952 in America and in Canada, and sold in jars with metal lids.
Kraft advertised that there were over 1,000 uses for Cheez Whiz (at one point, an exact number of 1,304 was bandied about.)
The classic jar size in North America was 1 pound (450 g.) The classic jar has been redone, and as of 2007 was 15 oz by weight / 425 g. In Canada, the jar sizes are now 250 g, 500 g, and 1 kg.
In the 1960s, the jar said “Pasteurized Process Cheese Spread.” Now, Kraft calls it “Process Cheese Sauce” in the United States and “Process Cheese Product” in Canada.
Cheez Whiz was sold in the UK only for a short while in the 1960s. Kraft does still sell a cheese spread in the UK, though, under the name of Kraft Dairylea Cheese Spread. It is sold in tubs, in the chiller section, and must be kept refrigerated.
Cheez Whiz wasn’t Kraft’s first cheese spread: from 1933 to 1958, Kraft sold “Swankyswigs”: cheese spreads in 5 oz (140 g) glass jars that could be used afterwards as drinking glasses. The glasses are now considered very collectible.
A classic snack at one time was Cheez Whiz on celery sticks.
