You can get by without a cable subscription these days and still watch plenty of video with the magic of the internet. Well, unless you have an oppressive data cap to deal with. Yuck. For everyone else, there's the streaming cable service Sling TV. It launched a while back with support for a few devices, which has been expanding steadily. Now, you can watch Sling TV via the Chromecast.

Sling TV is $20 monthly service that offers a few dozen cable channels without a traditional cable subscription. It comes with channels like Lifetime, ESPN, and TNT. Then there are add-ons for more sports, HBO, movies, and so on. The Sling TV app is being updated to support the Chromecast today. The web interface will get cast support soon.

New subscribers to Sling TV have the option of getting a free or discounted streaming device when you buy three months of service. This isn't new, but now that Chromecast support is official, the second gen Chromecast is one of the free devices you can choose from. If you already have a Chromecast, you can get a free two-month trial period instead of a week.
