Lots of things now come in smaller "standard" sizes.

The 1 pound can of coffee now contains 11-13 oz. The half gallon of ice cream is now 3 pints. The half gallon of orange juice is now 59 oz.

And the "best" way that a company has boosted its profit margin is Trop50 juices; they advertise "half the sugar" but what they really did was to dilute the juice by 50%.
