The Xbox One is much more than a video game console: it’s Microsoft’s answer to the Smart TV industry. A cable or satellite box can pass its signal through the Xbox via HDMI, which means that you can use your Xbox to watch live television.
The One includes a TV guide that can be navigated by voice and a trending section that displays the most popular shows both amongst your friends and the entire Xbox community. For example, asking the Xbox “What’s on MTV?” will pull up what’s playing on the network at that moment. The Instant Switch feature lets you switch between your Xbox and your TV without having to change the input. Just say "Xbox Watch TV" and the One will automatically switch to your television.
