McDonald's spent $300M+ on the Arch Deluxe, an 'adult' burger nobody wanted

In the mid-1990s, McDonald's worried that its image was too child-centered and that it was missing the growing adult market. Rather than adjust its existing menu or marketing, it decided to create a new line of more 'sophisticated' sandwiches. The flagship was the Arch Deluxe, launched in May 1996: a quarter-pound burger with peppered bacon, leaf lettuce, tomato, American cheese, onions, ketchup and 'Dijonnaise' (a Dijon-mustard-and-mayonnaise sauce).

McDonald's backed the launch with the largest advertising and promotional budget in fast-food history at the time — part of an estimated $300 million-plus spent on research, production and marketing (over $600 million in today's money). The ads, which showed adults rejecting kid-friendly food, were unconventional and confusing. Customers were also put off by the higher price, around $2.09 to $2.49, well above a typical McDonald's burger.

The Arch Deluxe flopped. Diners did not go to McDonald's for an upscale adult burger; they went for cheap, fast, familiar family food, and the new product asked them to want something the brand had spent decades training them not to expect. Sales disappointed, the line was scaled back, and on August 18, 2000, the Arch Deluxe was discontinued. It is remembered as one of the most expensive product failures of all time.
