Why is Google taking over Vegas for CES 2018?

Google doesn't usually have a big presence at CES, but that's changed in a big way this year. You can't help but notice that the monorail circling the Las Vegas Convention Center bears huge letters saying "Hey Google!" Just below, Google has set up a huge, multi-story monument to the Google Assistant booth in convention center parking lot. It's still under construction so it's hard to say exactly what's going on in there. Even though Google hasn't done much at CES in recent years, it makes sense for it to make a big splash this year. Earlier this week, the company announced that it has sold "more than one" Google Home device per second since the Home Mini launched in October.
