"It’s true that a few companies—Disney, say—have been able to consistently ride the Zeitgeist. But King has the misfortune to be in an industry where this is especially difficult, simply because it faces so much competition. “With traditional industries, it’s typically very expensive to get into them, and very expensive to actually make a product,” Michael Cusumano, a professor at the M.I.T. Sloan School of Management, told me. “But, with software, marginal costs are close to zero. That makes it easy for new competitors to enter the business.” Disney flourished not just because of creative genius but also because, historically, animation was incredibly labor-intensive and costly, and few companies could afford the distribution network and marketing operation necessary to get films in front of millions of people. Such high barriers to entry still exist in Hollywood or in traditional video-gaming. Only companies like Marvel or Activision can afford to make The Avengers or Call of Duty. Even then, things are chancy—that’s why studios love sequels—and failure is an ever-present threat. The company Harmonix, which launched Guitar Hero and Rock Band, games that in their day were as huge as Candy Crush, ended up being sold, after a few years, for fifty bucks and a pile of debt."
