Now Apple is about to get involved, TV streaming is becoming very big indeed. It's a perfect storm of wider acceptance, cheaper hardware and faster broadband speeds.
But which streaming box should you buy? We've rounded up five of the best for all your gogglebox needs.
1 Roku 2
Roku recently revamped its streaming box of tricks, giving it the same specs as the more expensive Roku 3, but without the enhanced remote control.
It also has new features galore. Roku Search lets you scour multiple streaming services at once for a film or TV show, including Netflix, Snagfilms and Popcornflix.
And Roku Feed lets you search for a film that's in cinemas now, and it'll notify you when it becomes available to stream, regardless of which service it's on. Very handy.
2 Amazon Fire TV Stick
Amazon's telly dongle does almost everything the Fire TV does, but is less than half the price. In fact, Amazon has cut the price again, from £35 to just £30. Bargain.
It's more powerful than Google's Chromecast, and brings tens of thousands of films and TV shows, millions of songs and hundreds of games to your TV.
It doesn't just work with Amazon either. You can watch Netflix, BBC iPlayer, YouTube, Sky News and more using it.
But if you want the same awesome voice control as its bigger brother, you'll have to shell out another £24.99 for the Amazon Fire TV Voice Remote. We would suggest you do – it's amazing.
3 Google Nexus Player
This is the first streaming box to run Android TV, Google's operating system that's optimised for the big screen. In other words, it'll give you access to Google Play's huge library of films, games, apps and TV shows.
Apps include Netflix, YouTube, TED, Vevo, and all the usual suspects from Google. Like Amazon's Fire TV, its remote has voice control, so just say the name of an actor, film, or even genre, and it'll find it for you. It also looks a bit like a spaceship.
4 Apple TV
Bit of a strange one, this. Apple TV is still one of the easiest-to-use streaming boxes around, but it hasn't been updated since 2012.
Suffice to say, it's getting a bit long in the tooth. Not to mention the fact Apple is set to launch a new model in the autumn, kitted out with its new TV streaming service.
You can beam content to it from your iPhone or iPad, and it streams in 1080p HD. It's probably worth waiting for the new one, unless you see it at a knockdown price.
5 Sky Now TV Box
Speaking of knockdown prices, Sky's Now TV Box is still one of the cheapest streaming boxes around. Sky hopes you'll buy its passes to Sky Sports and its film and entertainment channels too, but there's nothing to stop you just watching iPlayer on it.
Earlier this year, Sky let slip that a new model is coming soon, complete with an upgraded user interface.
But considering it's so cheap, we wouldn't be put off buying this one. It's the most affordable way to turn your standard set into a smart TV.
