You can now use Siri to search YouTube on your Apple TV

You can now ask Siri to search for YouTube videos on your Apple TV. 

This new feature, which was highlighted onstage at this week's WWDC, was expected to roll out this summer. But it's available right now for all fourth-generation Apple TVs.

Here's how to do it: Using the Siri remote, simply say "Search YouTube for Justin Bieber falls down" or "Show me E.T. as a charming '90s sitcom on YouTube" and Apple TV will enter your search commands into the YouTube app. 

You can search for specific videos, people, or channels. You can also search for more general terms, like "funny cat videos." Siri's dictation search also functions inside the YouTube app.

In our tests, the searches worked pretty well. Searching for a person or artist generally brought up their official channel first, followed by assorted videos.

It should be noted that a Siri search for YouTube on Apple TV is distinctly different from doing a more general Siri search that dives into content across the 650,000 shows and movies that Siri can currently search across more than 20 different services. This is by design. 

The thinking is that combining YouTube searches with more general searches would make the user experience too messy,
