 Let me ask you about the system of the AMP and exclusion of ad companies. I know it sounds technical, but it has an immense impact on Google and on consumers. Google started a condition treatment on Google search, a market where Google has 88% market share in the United States on publishers' adoption of another Google product, AMP. It did so right at the time when publishers finally found new tools to foster competition. When Google set the rules for AMP, it happened to block ad competitors and force them back into Google's own products. It conveniently also handed Google a treasure trove of publisher data. Publishers were facing a possible loss of 40 to 50% of incoming traffic with the top news and speed update rules unless they caved to those rules. That is quite simply a stunning abuse of Google market power, and I'd like to know what's your explanation. Senator, we introduced what we call AMP accelerated mobile pages, which I think you're referring to as for a simple reason that when websites load slowly and in particular when these websites were making a transition to mobile environments where it was new technology and some of these pages were loading extremely slowly, if a page loads slowly it does not monetize very well. The second that it takes seconds to load, people generally move away, and often it is the advertising that interferes with that load speed. We introduced AMP simply to help publishers and to try to give publishers a tool to allow their web pages to load more quickly. And we were proud of that tool. We never architected that tool so that it was a closed system. All of the tools that we use in our ad tech stack have to interoperate mainly because most of the publishers and advertisers multi-home with every other product that's operating in these systems. AMP was no different. We didn't design AMP so that it would only work with Google. We didn't design AMP so that it would somehow foreclose your access to other ways to sell your inventory. It was simply about trying to get web pages to load faster. And knowing that we've been clear since that AMP is not required to use any of our tools. My time has expired, but if we have another round of questioning, I hope we can follow up. Thank you, Mr. Chairman.
