Less than two years after the launch of its digital movie-viewing experience, Disney has announced an expansion on to two new platforms, increasing the availability of the entertainment giant’s films, just as it releases “Avengers: Age of Ultron” online.

The blockbuster film will be available starting Tuesday, Sept. 8, on previous platforms for Disney Movies Anywhere (DMA) and now two additional outlets: Amazon Video and Microsoft Movies.

Disney offerings will be available on several new devices, including the the Microsoft Xbox 360 and Amazon’s Fire tablets, Fire TV and Fire TV Stick. In addition, free DMA apps will launch for Roku and Android TV one week later, on September 15. That rollout will also arrive in tandem with the release of a popular Disney film — the live-action version of “Cinderella.”

The service had previously been available via iTunes, Google Play and Walmart’s Vudu. Among the devices that can access Disney digital movies are iOS, Apple TV, Android Mobile and Tablet, select Amazon Kindle tablets, Amazon Fire TV and Fire TV Stick, Microsoft Xbox 360, Android TV (from Sept. 15), Google Chromecast, Roku (as of Sept. 15) and laptop/desktop computers.

As part of its promotion for the service, new accounts will be eligible for a free copy of Disney-Pixar’s “Monsters, Inc.”

“We’re thrilled to bring these new partners to Disney Movies Anywhere, expanding its reach into the living room and beyond with an unprecedented Disney experience that is both easy and fun,” said Janice Marinelli, president of Disney and ABC’s Home Entertainment & Television Distribution. “As consumers seek to build their digital libraries and protect their purchases for the long term, Disney Movies Anywhere makes it easier than ever to buy once and watch anywhere.”
