I thought you were kidding, but then I checked. Indeed, on Google, android.com/kitkat comes up first, then kitkat.com. On DDG and Bing, search results are still all about the snack.

For KitKat (which is the OS name) I see android.com/kitkat first, kitkat.com second and Wikipedia third.

For Kit Kat, which is the candy bar, I see Wikipedia first, followed by kitkat.com and android.com/kitkat third.

Their SEO isn't dead, but that space is and will be increasingly significant.

I'm having a harder time telling the natural hits from the ads these days but in mine it's kitkat.com first followed by "news for kitkat", then wikipedia, hershey's, and finally android.

This is what my Google SERP looks like in Safari, not logged into Google:

(The Kitkat.com listing has a different description than it did an hour a go, because of the Android tie-in. But even then, the Google Android page was higher up the list.)
