Variety: Fox Broadcasting’s Internet-streaming service is now available through Google’s Chromecast adapter, providing access to full episodes of the broadcaster’s current and recent shows, including the entire first season of smash hit “Empire.” But there’s a catch: Users must subscribe to a participating cable, satellite or telco pay-TV provider in order to watch most of the Fox content through Chromecast. That includes access to the full 12-episode run of frosh sensation “Empire,” the music-biz drama starring Terrence Howard and Taraji P. Henson.
