In the Grip of the New Monopolists via WSJ

As I have eluded to in previous posts, the story of the Internet’s short-term future and the economy it supports will be about Antitrust.  This article from the Wall Street Journal eloquently sets the stage for the legal, business, and economic battles to come: 

The Internet has long been held up as a model for what the free market is supposed to look like—competition in its purest form. So why does it look increasingly like a Monopoly board? Most of the major sectors today are controlled by one dominant company or an oligopoly. Google “owns” search; Facebook, social networking; eBay rules auctions; Apple dominates online content delivery; Amazon, retail; and so on.

The rise of the app (a dedicated program that runs on a mobile device or Facebook) may seem to challenge the neat sorting of functions among a handful of firms, but even this development is part of the larger trend. To stay alive, all apps must secure a place on a monopolist’s platform, thus strengthening the monopolist’s market dominance.
Internet industries develop pretty much like any other industry that depends on a network: A single firm can dominate the market if the product becomes more valuable to each user as the number of users rises. Such networks have a natural tendency to grow, and that growth leads to dominance. That was the key to Western Union’s telegraph monopoly in the 19th century and to the telephone monopoly of its successor, AT&T. The Bell lines simply reached more people than anyone else’s, so ever more customers came to depend on them in a feedback loop of expanding market share. The more customers they reached, the more impervious the firm became to challengers.
