Does your TV have one-touch access to apps for BBC iPlayer, YouTube, Netflix, Lovefilm and Blinkbox? Not all smart, connected TVs are equal - they differ greatly in looks and apps - but all can get online, most using Wi-Fi.
There is no industry standard for smart TV, so every brand of television has a different platform of apps, though expect to find everything from sport, weather and on-demand video and movies to 3D content, games and social networking.
What's the best connected TV platform? That will depend on what you're after; some smart TV systems excel with a wide range of on-demand apps from UK TV channels, others with on-demand movies.
We've ranked the UK's major connected TV platforms in descending order, putting just as much emphasis on ease of use as app selection, to help you as you buy into a whole new generation of online television.
