Wall Street Journal: The New York Times has shifted its digital strategy toward courting young readers with free content rather than trying to turn them into subscribers right away. That approach has the Times experimenting, to varying degrees, with making its content available across a multitude of platforms, from Facebook’s Instant Articles to Apple’s coming News app. The moves, however, leave the Times with a delicate balancing act: The paper is trying to boost its web and mobile audience to bolster ad sales without undermining a steadily growing digital subscription business. The newspaper’s top digital executives argue that aggressively going after younger readers on platforms outside of the Times will persuade some to subscribe.
