Chromecast is definitely a great piece of hardware, and at the normal cost of $35(sometimes less of you can find it on a deal or a sale)it's a steal especially for all the content that it can help you bring to the big screen through streaming. There's already plenty of media apps available for the Chromecast for streaming movies, TV, and music, and even some games like the wonderful CardCast. As of today you'll be able to serve your Chromecast up a healthy daily dose of news and more popular mainstream programming through the NPR One and Watch ABC applications, as they're slated to get the compatibility update for Chromecast today, and should already be live.
NPR One is a go to application for listening to news radio and providing a special curated experience making it easy to listen to all the talk and news radio shows you love through an easy to use interface. The content is tailored to you, so you can set your preferences and the app will grab stuff for you based on that information. Now having that ability on the Chromecast means that you can enjoy those news and talk radio shows through the big screen if you're at home while you do other things.
Watch ABC should be pretty self explanatory, as it brings mainstream popular programming from ABC to your Android device, and now the big screen through the Chromecast support that's coming. You'll be able to watch some of your favorite shows just like you were watching them on ABC via your cable provider but all controlled through the interface of your Android app, which is one of the best features of the Chromecast, the controls, as simply interacting with your device will take care of everything on the big screen. For some people the update to the apps may already show as the updates should be live as of now, if they don't pop up simply close out the Play Store from recent apps and check again. If you use NPR One the app is free, Watch ABC however requires you to have cable with a connected account to use the app and stream shows to the TV.
