The New Yorker and the Atlantic have never been known for their business coverage, so when both magazines published long articles about Amazon.com Inc. in their current issues it signaled that something is in the air. That something is antitrust.

More precisely, what's in the air is the question of what the government should do to rein in the tremendous power of the big four tech companies: Facebook Inc., Alphabet Inc.'s Google, Apple Inc. and Amazon.

Once the province of think tanks and law reviews, this topic has become such a public concern that 48 of the 50 state attorneys general are conducting antitrust investigations, presidential hopefuls are calling for tech giants to be broken up, and general interest magazines like, well, the New Yorker and the Atlantic are asking whether the companies abuse their market power. In this particular case, the magazines are asking it about Amazon.
