For years, cord cutters had to make a choice: could they live without live TV? There were plenty of on-demand alternatives in the late 2000s and early 2010s, but cable and satellite still had a stranglehold on live TV, including live sports. Then, in 2015, Sling TV changed everything. What is Sling TV? It's a live TV streaming service, or skinny bundle. It was the first major service of its type when it debuted, but now Sling TV has lots of competition. It's fair to wonder if Sling TV is the right skinny bundle for you, so let's talk a little about how Sling TV works. Below, we'll cover everything from what channels are on Sling TV to how to cancel Sling TV.What Channels Are on Sling TV?Sling TV debuted with a set of channels that have since become staples of skinny bundles: AMC, ESPN, and TBS, to name just a few. But as skinny bundle options have expanded and improved, Sling TV has kept pace admirably. Sling TV has added local broadcasts of major networks like NBC. It has netted some regional sports networks, too, which are available in select markets. And it offers you way to subscribe to everything from famous premium channels like HBO to niche streaming services like CuriosityStream.Here's a few of the highlights from Sling TV's channel selection:ChannelsAMCCNNComedy CentralESPNFoxHGTVNBCTBSOf course, that's far from a full list. You can find a more comprehensive accounting of what channels are on Sling TV by checking out our Sling TV channel list.Keep in mind that Sling TV offers a few different subscription options. There are two entry-level base packages, “Sling Orange” and “Sling Blue,” each of which offer certain channels that the other does not. Combine the two, and you'll get all of the base-bundle channels at a discounted rate.Then there are the “Extras” — add-on packages that feature standalone premium channels and subscriptions or little mini-bundles of similarly themed channels. You'll find more niche channels in the Extras. You can add Extras to either or both base bundle, and you can pick and choose which Extras you want, so it's easy to build a custom Sling TV subscription that tailors your channel selection to your personal tastes.You'll find more details on which channels fall into which packages in our Sling TV channel list. We'll also talk more about bundles and pricing in our How Much Does Sling TV Cost? section.What Devices Can I Use to Watch Sling TV?Sling TV has been around since 2015, which has given it plenty of time to build out great apps for all of the most popular streaming platforms and devices. As a result, Sling TV has really robust platform support. There's a very good chance that you can watch Sling TV using your current favorite streaming device, whether that be a Roku, Chromecast, iPhone, or other device.Want details? We've got details.

For one, skinny bundles are more convenient than cable: you can watch them on all sorts of different devices and time-shift TV with Sling TV's cloud DVR (an Extra, or add-on, feature), so it's easy to watch live TV on your time and wherever you are.But perhaps the most important reason that people choose Sling TV over cable or satellite is that Sling TV offers a more affordable live TV experience. But how affordable is it? How much does Sling TV cost?Sling TV's most basic bundles — Sling Orange and Sling Blue — cost $25 per month each. If you sign up for both, you'll get all of the base-package channels for a discounted rate of $40 per month.Once you have either or both base bundles, you can tack on Extras (add-on packages). The Extras can cost anywhere from $5 per month to $15 per month or more. You can add HBO, Showtime, a whole bundle of sports channels, or some or all of the above (and much more) — it's entirely up to you.Deals on Sling TVSling TV is a pretty cost-effective thing, but you can save even more money if you're savvy about when you sign up for Sling TV and pounce on one of the service's deals and promotions.

Well, in any event, it has got one: on top of everything else, Sling TV doesn't trap you into a long-term contract.When you sign up for Sling TV, you'll be billed at the beginning of each month and will enjoy live TV all month long. The process repeats unless and until you decide that you want out of the deal. When that time comes, you can just cancel Sling TV (we'll show you how in a moment) and you and your live TV streaming service will part ways at the end of the current billing period. The “current billing period” is just whatever month you most recently paid for. You'll never pay again once you cancel, but if you cancel right after you paid for the upcoming month, your Sling TV subscription will run through the end of that month (you won't get your last payment back).How to Cancel Sling TVWhether you've decided to move on from the service or just want to get out of your free trial before you're billed, we've got you covered. Here's how to cancel Sling TV.Start by heading to Sling TV's website and signing in. Then, navigate to the My Account page and click Cancel Subscription. Sling TV will beg you to stay and ask you why you're leaving, but keep clicking the cancel buttons and they'll eventually let you go.As we mentioned in the last section, cancelling Sling TV means that you're stopping all future payments. It won't do anything about payments you've already made, naturally, but you'll get what you paid for: Sling TV will end your service only when the month that you most recently paid for ends. If you're considering cancelling Sling TV, just remember that you might want to do so before your next payment goes through.Of course, if you cancel before the end of your free trial, that free week is your current “billing” period, and you won't be billed at all. That's what “free” means, after all!All About Sling TVSling TV has been a hit with cord cutters since it debuted back in 2015.
