Franklin Foer in The Atlantic:
Where in the pantheon of American commercial titans does Jeffrey Bezos belong? Andrew Carnegie’s hearths forged the steel that became the skeleton of the railroad and the city. John D. Rockefeller refined 90 percent of American oil, which supplied the pre-electric nation with light. Bill Gates created a program that was considered a prerequisite for turning on a computer. At 55, Bezos has never dominated a major market as thoroughly as any of these forebears, and while he is presently the richest man on the planet, he has less wealth than Gates did at his zenith. Yet Rockefeller largely contented himself with oil wells, pump stations, and railcars; Gates’s fortune depended on an operating system. The scope of the empire the founder and CEO of Amazon has built is wider. Indeed, it is without precedent in the long history of American capitalism.
Today, Bezos controls nearly 40 percent of all e-commerce in the United States. More product searches are conducted on Amazon than on Google, which has allowed Bezos to build an advertising business as valuable as the entirety of IBM. One estimate has Amazon Web Services controlling almost half of the cloud-computing industry—institutions as varied as General Electric, Unilever, and even the CIA rely on its servers. Forty-two percent of paper book sales and a third of the market for streaming video are controlled by the company; Twitch, its video platform popular among gamers, attracts 15 million users a day. Add The Washington Post to this portfolio and Bezos is, at a minimum, a rival to the likes of Disney’s Bob Iger or the suits at AT&T, and arguably the most powerful man in American culture.
