Crain’s Chicago Business: The Apple Watch has already sparked an arms race among media companies vying for attention on your wrist. One of the latest to join the fray is Tribune Publishing, which is rolling out an app for eight of its newspapers, from the big ones like the Los Angeles Times and Chicago Tribune to the relatively small Morning Call in Allentown, Pa. Apple Watch owners in the cities that Tribune covers will receive breaking news alerts for their hometowns. Tribune also aims to set itself apart with a “listen” feature, where users can tap a specific story on the Watch and have Siri read it aloud from the iPhone.
