These predictions shouldn't come as revelations. IT vendors, despite their collective superiority complex, aren't impervious to the economic forces that reshape every other maturing industry. Whether companies make servers or switches or cars or light fixtures, whether they provide software or bandwidth or financial advice or air travel, economies of scale dictate that a handful will eventually dominate, often with homogenized products.
But consolidation doesn't preclude innovation. Even in industries with the mightiest giants, start-ups fill market niches and keep the behemoths on their toes. Wal-Mart may be the world's biggest company--its 2002 revenue of $244 billion represented 2.3 percent of U.S. GNP--but it's hardly resting on its laurels, launching and testing all kinds of new services. Wal-Mart may have wiped out thousands of mom-and-pop stores, but thousands of specialty retailers still flourish in its shadow, while big discounters such as Target and Costco are holding their own. No market position is unassailable. Just 20 years ago, Sears (whose 1983 revenue accounted for 1 percent of GNP) was considered invincible; then Wal-Mart reinvented the industry.
Even as profit margins narrow, innovators will pile in. What were Southwest and JetBlue thinking when they decided they could make a go at the profitless airline business? They were thinking clearly, it turns out. Both carriers are quite healthy today thanks to their leaner cost structures and superior service, while the industry "leaders" are nearly bankrupt.
