Steve Ballmer has been CEO of Microsoft since 2000. During his tenure, Microsoft came out with Windows Vista, perhaps the most unsuccessful operating system in modern history (Windows ME doesn’t count, since Microsoft’s core customer base was using NT/2000); it tried a “Microsoft inside” strategy in digital music and, when that failed, launched the Zune, which also failed; it watched Firefox (and Safari and Chrome) eat a large chunk of its lunch in Internet browsers, the application most people use more than everything else put together; it launched Windows Live, a marketing strategy with no noun behind it, which completely flopped at whatever it was supposed to do; it got blown away in Internet search to the point where it had to re-launch as Bing, a plucky underdog; and in mobile phones, which everyone has known for a decade would be the next big thing, it stuck with its bloated, awkward Windows Mobile for far too long, letting everyone (RIM, Apple, Google, and even Palm) pass it by to the point where it has no customer base left. (BlackBerry rules the corporate market, Microsoft’s traditional stomping grounds.) Recently I saw a headline saying that Microsoft is going to try to relaunch Hotmail to make it cool. Really, why bother?
