Google’s Chromecast streaming-media dongle for HDTVs has added support for three Disney cable nets — as well as videogame webcaster Twitch, music streaming service iHeartRadio and DramaFever — as the race to bring more content to TVs continues apace.

The $35 Chromecast now supports Watch Disney, Watch Disney Junior and Watch Disney XD apps. “So now you’ll be able to watch ‘Girl Meets World,’ ‘Doc McStuffins’ and ‘Star Wars Rebels’ on-demand from the Disney Android and iOS apps,” Shanna Preve, Chromecast director of global content, wrote in a blog post announcing the additions.

To watch the Disney networks’ livestreams or recent episodes, users must sign in with a participating pay-TV provider account. Last month, Google added support for Disney’s Watch ABC as well as NPR One.

Also now available on Chromecast are iHeartRadio, whose app provides more than 1,500 live radio stations from all over the U.S.; Twitch, which Amazon.com recently acquired for $970 million, to stream live video gameplay to the TV from the web, Android and iOS apps; and DramaFever, a subscription VOD service that provides more than 15,000 TV episodes of international drama series.

Chromecast, which debuted in July 2013, now supports more than 350 apps and services, including Netflix, YouTube, HBO Go, Pandora, Hulu Plus and WatchESPN. In addition, the device, which plugs into an HDMI port on the back of television, can stream any tab from a Chrome browser to a TV. And according to Google, more than 6,000 developers are actively developing more than 10,000 Google Cast-enabled apps across Android, iOS and Chrome.

Google’s inexpensive dongle competes with Internet set-tops including Apple TV, Roku and Amazon’s Fire TV — but none has run away as the market leader just yet.

As of this July, Google had sold 3.8 million Chromecast devices over the previous 12 months worldwide, according to research firm Parks Associates. That’s fewer than Roku’s 10 million boxes shipped to date, while Apple CEO Tim Cook earlier this spring claimed the tech giant had sold more than 20 million Apple TVs. The Amazon Fire TV, meanwhile, launched this April.

According to an NPD Group commissioned by Roku conducted in July, Roku leads on usage with an aggregate 37 million hours of video streamed weekly — versus Apple TV at 15 million hours, Chromecast at 12 million hours and Amazon Fire TV at 6 million hours.
