Which of the following was mentioned as an example of a product failure?

The example of a product failure often highlighted is Watermelon Oreos. This product was introduced as a limited edition flavor by Oreo, intending to tap into the seasonal appeal of summer. However, despite the company's efforts at marketing, it failed to resonate with consumers and did not achieve the expected sales targets. This case is cited in discussions about marketing missteps because it illustrates how taste preferences can significantly impact a product's success, especially for a brand like Oreo that is traditionally associated with classic flavors. The unusual combination of watermelon and cookie elements proved to be unappealing to most consumers, making it a notable example of a product failure in the snack industry.

In contrast, Nissan Murano, Pepsi Blue, and Coca-Cola Zero each have their own merits as products, with varying levels of market presence and consumer acceptance, but they did not experience the same level of failure as Watermelon Oreos.
