Adult Swim, the adult-oriented nighttime side of Cartoon Network, has just released a new app for all Amazon Fire TVs, Fire TV Sticks, and Fire TV Edition televisions. The app a healthy mix of free ad-support content as well as content that requires logging in with a TV provider. A marathon feature within the app lets you select a single show and watch an endless stream of episodes from that show that you have little control over. There is, of course, regular on-demand access to select episodes as well. If you activate the app, you’ll also be able to access live streams of what is airing on the network’s cable channel, called a TV simulcast, as well as an all-day stream of content. A program guide for both streams is available to see what is scheduled to air in the future.
