All you need to do is fire up the HBO Now app on your mobile device, find a video you want to watch, and tap the cast icon to send it to a TV with a Chromecast device connected.
That makes the Chromecast one of the cheapest, simplest devices capable of streaming HBO programming to a TV. Want to go even cheaper? Groupon is currently selling refurbished Chromecast sticks for $20.
Google says HBO Now is just one of the new apps available for Chromecast though. Food Network, Watch Travel Channel, and Pokemon TV apps are also now available, as well as new games including Tricky Titans, FitFlap, and Catch Phrase Blitz.
Online image editor Pixlr also now works with Chromecast, letting you crop, rotate, and make other adjustments to images displayed on your TV.
