So Apple has decided that Steve Jobs will not give the Macworld Expo 2009 keynote address in a few weeks, and that the company will pull out of the 25-year-old show altogether after the 2009 edition. And speculation runs rampant across the Web and print media worlds, about (1) Steve Job's health and (2) that of Macworld Expo itself. I'll ignore issue (1) because it's none of my business, and focus on issue (2).
The large computer industry trade show has been a dying dinosaur for years, but has stubbornly hung on in many cases. However, there are now too many factors mitigating against the success of such events. These range from the abilities of companies such as Apple to turn retail stores and Web sites into far more manageable, controllable, and profitable "mini-expos" to growing requirements to reduce or eliminate costly, low-productivity business travel. (I mean, the MacBook Pro on which I'm composing this very screed already has built-in Internet connectivity, a microphone AND a camera...)
But don't cry for Macworld just yet. There is an awful lot of value to be gotten out of the event, even should Apple disappear from it entirely as a participant, or radically reduce its participation. I'm old enough to remember when networking pioneer all but owned the NetWorld trade show, but that event retained value beyond Novell itself, especially when it was combined with Interop, another pioneering big industry event. So there's semi-relevant precedent for the possibility of an Apple-free (or "Apple-reduced") Macworld continuing on successfully, at least for a while.
All depends on how Macworld Expo 2009 actually plays out, and what Apple does, if anything, before, at, and after said event. (If you want to read similar, more granular, and "closer-to-home" musings on this subject, I highly recommend "Apple at Expo: What went wrong?" by Jason Snell of Macworld.com, a corporate cousin of the company that runs Macworld Expo.) But regardless of how things play out at Macworld, what's happened to Macworld is definitely indicative of a larger truth: with few if any exceptions, the larger and/or more focused on a single vendor the trade show, the more likely that its days are numbered. And those numbers, if used to measure years of remaining longevity, are in the low to very low single digits, at best.
