Some years ago at a Customers Seminar organized by Agilent Technologies, right in the middle of the Bubble tornado, the keynote speech was held by one of the key executives at UK telco BT (sorry, don't remember his name nor his actual job). We were in the early 2000, and the guy was telling us that the next big thing in mobile communications was going to be SMS, MMS, and IM messaging. Heck, the iPhone was still a dream, my Ericsson was featuring a 2-colors 2-lines liquid crystal display (well, you know what I mean), and MySpace was just the name of one of my directories on my PC...
BT found out that teenagers were to be the largest group of cell phones users, spending their time to chat with their friends all day (and night) long.
Almost all of us in the audience were kind of dubitative : no way the kids were to become so IM-addict that they would spend hours typing on their cell phones. Well, six years after, BT was right, and we were wrong.
That's why this article is a must-read for all of us working on changing the World. Its title : "Kids say e-mail is, like, soooo dead.". Got it, folks ?
