Thank you, Carlos, a lot in those questions. So starting with Sites revenue and where we see the opportunities there, obviously Sites revenue up 24% year on year includes the currency impact. And as Sundar and I both commented on, the biggest driver again this quarter was Mobile Search. We do continue to have solid growth in Desktop, Tablet. And we have strength in YouTube, particularly video advertising, both in our TrueView product and increasingly from Google Preferred. As we've talked about every quarter since the third quarter of last year, we have benefited from the change to ad formats on Mobile that we made in third quarter of last year, and that is evident yet again this quarter. Then, as per your question, going back to that third quarter of 2015 when we made the change in ad formats on Mobile, our growth rate meaningfully accelerated. And as we've noted in each subsequent quarter, that change has been the primary driver of the higher year-on-year revenue growth rate. But importantly, as you've seen over the last several quarters, we're benefiting not just from the higher growth rate but also from the durability of the impact of the change. So that's really underscoring the efficacy of these ads for users, as per Sundar's comments, and it's reflected in revenues running at a higher level. And you can see where the revenue growth rate was prior to the third quarter introduction. I'll let you do your own forecasting, but when comparing growth rates, we're obviously at a higher revenue base versus last year. And then Sundar talked about some of the recent events that we've had. Innovation is core to everything we're doing. We've launched several changes to ad formats and tools just a few days ago. As the team discussed at the Google Performance Summit, we believe the changes should result in a better, more useful experience for users and better performance for advertisers. And so that just continues to be core to the way we're looking at the business with a lot of incremental opportunity. And then on your Fiber and CapEx question, look, we continue to see Fiber as a huge market opportunity. We're focused on creating abundant connectivity on networks that are always fast and always open, as we've talked about, and we're continuing to work closely with cities given their excitement. We're also continuing to push the frontier with tech innovation, as you noted in your question, and different execution paths. So as you said in the question, we're exploring both Fiber and wireless, and you may have seen our recent acquisition of Webpass. So we want to make sure we're executing against a very large and attractive market in the most effective and efficient manner. We did start adding customers in Charlotte in July. And so again, we view it as a big opportunity. We're being thoughtful and deliberate in our execution path.
