Google is readying a newsstand for Android devices even as Apple is racing to make important concessions on its iTunes news subscription plans, multiple sources said Sunday night. The search engine is reportedly hoping to race Apple to a central periodical platform and would aggregate phone- and tablet-optimized magazine or newspaper apps in a central place. The company would try to lure publishers away from Apple by undercutting its own usual 30 percent cut, the WSJ heard, and by agreeing to give private subscriber information that Apple has so far refused.
