Roku has begun rolling out its Amazon Prime-like premium video subscriptions on The Roku Channel, after announcing the addition earlier this month. All supported devices can expect to receive an update over the next few weeks, starting with Roku players and concluding with Roku TV models.

Premium Subscriptions enable users to add subscriptions from more than entertainment services, including Showtime, Starz, and Epix. Those that sign up for any of the aforementioned three networks before 31 March 2019 will gain access to a 30-day free trial of those services.

“We’ve made subscription streaming easy for our customers and are putting them in control. Now there is one place on the Roku platform where users can seamlessly access both free and premium entertainment, with one click sign-up, easy subscription management and a single monthly bill,” said Rob Holmes, VP of programming and engagement at Roku. “The Roku Channel already delivers a great, free ad-supported experience for our users and a valuable distribution opportunity for our content partners. With the addition of Premium Subscriptions, The Roku Channel will be a better experience for our users and even more valuable for our partners.”

Initial subscription partners include Showtime, Starz, Epix, CollegeHumor’s Dropout, Dox, Monsters and Nightmares, Magnolia Selects, Noggin, Tastemade, Viewster Anime, and more.

In addition to launching Premium Subscriptions, The Roku Channel is now available from within the iOS version of the Roku mobile app. Android devices are expected to gain access in mid-February.
