Multiple outlets report that PepsiCo briefly enters the chocolate drink market with Devil Shake in 1966, aiming to compete with Yoo-hoo. The accounts say the product is introduced as Pepsi’s attempt to take on the established chocolate drink brand and capture a similar consumer niche. However, the drink does not perform as expected. Sources agree that Pepsi discontinues Devil Shake within about a year of its launch. One outlet further reports that Pepsi sells its Devil Shake operations for a token amount, described as one dollar, signaling an early exit from the business. Overall, the story centers on a short-lived PepsiCo experiment in a chocolate-flavored beverage category, followed by a rapid discontinuation and divestment. The reports do not provide additional performance figures, specific sales details, or reasons for the withdrawal beyond the rapid discontinuation and sale described in the coverage.
