Blue bubbles feature in Apple US antitrust case

Earlier this month the European Commission fined Apple €1.8 billion over the way the company's App Store deals with music streaming service providers, which in practice boils down to Spotify.

Last week the US Justice Department piled on. It says Apple illegally exploits its monopoly in the phone market.

The assumption here is odd.

A questionable monopoly

Apple is arguably the world's most important phone maker. It is huge. But it is not a monopoly.

It accounts for more than half of all phones sold in the US.
