Five new product failures are analyzed: Crystal Pepsi, Betamax, New Coke, Colgate Kitchen Entrees, and McDonald's Arch Deluxe burger. Crystal Pepsi and New Coke failed because consumers did not find them similar enough to regular cola in taste and branding. Betamax failed due to inferior marketing compared to the competing VHS format. Colgate Kitchen Entrees inappropriately extended the toothpaste brand into food. The Arch Deluxe targeted the wrong adult demographic who did not want to pay more for slightly different burgers. In general, these products failed because marketers inadequately assessed consumer preferences and brand positioning.
