In the world of streaming video, no service is more important than Netflix. When Netflix released its streaming service way back in 2007, it was the only service of its kind. A lot has changed since then, of course, but Netflix is still delivering top-notch streaming movies and TV shows to its millions upon millions of subscribers. Netflix has original shows and movies of its own, now, and can be viewed on devices as diverse as your iPhone and your Roku. “What is Netflix?” is a question that virtually nobody has to ask, but there still might be some things you don't yet know about the world's most popular streaming service. Here's our complete guide to Netflix, including information about the best Netflix original series, how much Netflix costs, and how to cancel Netflix.What Shows and Movies Are on Netflix?Netflix is full of great content, just as it always has been. But modern Netflix also has some stuff that the streaming service's original 2007 incarnation did not have: original movies and TV shows. With the cost of licensed content rising, original productions have become a key part of Netflix's long-term strategy, and the company has invested in its own shows and movies in a big way. The result has been a huge crop of original series. The originals come in all sorts of genres — and, truth be told, all different levels of quality. But some of Netflix's best original series and movies are real classics that rival the best stuff that big Hollywood studios and competitors like HBO can offer.Here are some of the highlights of Netflix's catalog. We're focusing on original series, but Netflix also has plenty of licensed content.

The original Roku was built with Netflix in mind, and Netflix has done a great job of ensuring that it has a quality app for every major platform that has rolled out since. On top of that, Netflix works great in your browser, on your smartphone, on your tablet, and on other devices you may want to stream on.

But between inflation, the growing expense of competitive streaming rights deals and original series spending, and the inevitable growth of a profitable company, Netflix had to bump its prices up a few times.Despite all of that, Netflix is still remarkably cheap. Its pricing is in line with that of many of its competitors — this despite the fact that, to many, Netflix is an indispensible service that's on another level from its competition.So let's get down to brass tacks: how much does Netflix cost? Well, that depends on what plan you choose. Netflix's most popular plan costs $10.99, but you can pay more or less than that depending on what features you can and can't live without. Here's the full breakdown:The Basic plan costs $7.99. Your streaming is unlimited, but you can only stream on one device at a time and only get standard-definition video.Standard costs $10.99.

We know both those words, but when you put them together they just… don't make sense.Netflix has been killing cable for years, and one of the reasons why is the fact that Netflix has no long-term contracts to worry about. You pay for Netflix by the month, and you can cancel at any time. If you cancel, your subscription will end at the end of your current billing period.In other words, if you just paid for the coming month, you won't get that money back — but you will have Netflix until the end of the month. If you cancel right before you would have paid, your service will end sooner and you won't have to pay any more.How to Cancel NetflixCanceling Netflix isn't hard, but let's break it down real quick just to make sure that you're doing everything right.
