About a month back, I wrote this blog entry about the efforts to revive interest in Tamagotchi digital pet toys that were popular about 10 years back. Largely, the Tamogotchi brand seems like ancient history. Today, the New York Times reports on the successful resuscitation of the Pokemon brand, which was also wildly popular about a decade back. Ultimately, it looks like the company's change in fortune came from the introduction of new product. But there's also a bit at the end about the ill-effects of overexposure, which is a good reminder PR and business execs alike.
