Finally, this is a case study of open and closed approaches. Games consoles’ closed ecosystem delivered huge innovation in games, but not in much else. The web’s open, permissionless innovation beat the closed, top-down visions of interactive TV and the information superhighway. The more abstracted, simplified and closed UX model of smartphones and especially iOS helps to take them to a much broader audience than the PC could reach, and the relative safety of installing an app due to that ‘closed’ aspect enables billions of installs and a new route to market for video. It’s not that open or closed win, but that you need the right kind of open in the right place.
