Google's Play Store shake-up looms after Supreme Court refuses to delay overhaul of the monopoly

The U.S. Supreme Court on Monday refused to protect Google from a year-old order requiring a major makeover of its Android app store that's designed to unleash more competition against a system that a jury declared an illegal monopoly.

The rebuff delivered in a one-sentence decision by the Supreme Court means Google will soon have to start an overhaul of its Play Store for the apps running on the Android software that powers most smartphones that compete against Apple's iPhone in the U.S.
