Updated: Now TV: what is it and how do you get it?

Available since July 2012, Now TV is an internet-based instant streaming TV service powered by satellite provider Sky that's designed to persuade you to switch from Lovefilm and Netflix, but it will soon supply sports as well as movies.Available across multiple devices, it's based around Sky Movies - and promises the best films first. There's no contract, but it's not exactly cheap. Here we explain all about Now TV.Where can I get Now TV?As well as being accessible through any web browser, there are Now TV apps for iOS and Android devices (though it's not on Apple TV) so Now TV can get into all smartphones and tablets on Wi-Fi or 3G internet connections. But unless your device has an HDMI output to hook up to a TV, the service arguably makes most sense on set-top boxes and games consoles. Now TV apps can be downloaded to YouView boxes from Humax and BT, and the Roku streaming boxes such as the Roku 2 XS and Roku LT. Those with an Xbox Live subscription can download the Now TV app to an Xbox 360 games console.Although it's designed to work across all of these devices, you can only register two devices at any one time. These can be changed, but only once per month, so it's not a case of 'anything, anywhere, anytime'. Now TV is also strictly limited to the UK, so there's no way of watching movies while abroad.What can I watch on Now TV?Now TV is all about Sky Movies.
