Sling TV, the Internet-based TV service that was first announced by Dish at CES 2015, is now available for anyone to access following an invite-only beta testing period. Dish has also announced that AMC has been added to its list of networks that can be accessed with its basic fee of $20 a month.
Sling TV (not to be confused with the Slingbox television set-top box), can be accessed on the Roku set top box and Roku Stick, along with Roku-based smart TVs.. Dish is offering users a seven day free trial, so you can see if this "cord-cutting" option is right for you before paying the monthly fee. In addition to the $20 tier, which offers a collection of 15 channels, customers can pay for additional collections of sports, news and kids channel for $5 a month each.
