Parkay is a margarine made by ConAgra Foods. It was introduced in 1937. It is available in spreadable, sprayable and squeezeable forms. Prior to 1999, this brand was made by Kraft Foods. The product label states that the product contains 0g trans fat. Yet the ingredients listed on the package include hydrogenated and partially hydrogenated oils. The Food and Drug Administration allows food manufacturers to claim '0g of trans fats,' so long as each serving of the product has less than half a gram of trans fat. Starting in 1973, a long-running advertising campaign was introduced for Parkay featuring a mechanically animated 'talking tub' of the product. A typical ad depicted a sort of humorous verbal sparring match between a character mentioning Parkay, and the talking package (its lid flipping up in imitaion of a mouth) correcting him by saying 'butter' in a deapan voice. The tagline: 'Parkay Margarine from Kraft--the flavor says...' [package] '...butter.'
