Twenty years ago for the 92/93 New Year’s, Yuriko and I were in Boston. We spent some of New Year’s Eve downtown, including a short visit to the Massachusetts State House. Out in front of the building, PepsiCo was busy marketing a new drink, Crystal Pepsi.

Even then, the detachable pop-top was a thing of the past, but the costume wouldn’t have worked without it. I returned to Japan shortly afterward and thought little about Crystal Pepsi. Years later I learned that it was a famed new-product flop.

Reading about that flop now, I found an interview with Yum! Brands CEO David Novak in Fast Company in 2007. He’s credited with creating Crystal Pepsi, and when asked about the flop, his money quote is: “People were saying we should stop and address some issues along the way, and they were right. It would have been nice if I’d made sure the product tasted good.”
