I can show you another stack that have proven successful. One of the things I've noticed lately is airlines reacting to each others pricing on a daily if not hourly basis. One airline will offer a deeply discounted special on a Dallas to Seattle flight via their website. Within hours, several other airlines will counter. It has to do with which flights come up first in the online booking engines.
Technology companies fall in the same category.
A new security breach is discovered with MicroSoft's HotMail. Instantly, troops of programmers are deployed to fix the bug and issue a patch. Such sudden changes in technology, or in the economics of technology can be trumpeted worldwide in seconds, where it would have taken months or weeks just a few years ago. But scary as this volatility may seem, it brings with it new opportunities. The airlines make much higher margins off their Internet bookings because the information goes straight from you into their computers with no agent.
