Google has a lot of initiatives going on around wireless. What is its strategy when it comes to mobile? Does it differ from the company's traditional Internet strategy?

    Sacca: The company's mission statement is to organize all the world's information, make it universally accessible and useful. So mobile really homes in on the universally accessible piece, which is answering questions like, what information do you need when you're not at your desk or when you're not tethered to your DSL or cable connection? What device will you use to access it? What are the input or output constraints on that device? And how can we improve and tailor our services for that environment?

    So you've seen us launch some really cool mapping stuff with Google Mobile Maps, which embeds local search, traffic and driving directions into a mapping format that is really accessible on a mobile device. And I think it's been shown to be a pretty valuable service in that context. So we will continue to pursue that strategy.

    The universally accessible part also means that we are trying to do what we can to remove obstacles that are standing in the way of making the Internet available to the largest number of people possible. The technology is there to make the Internet available to everyone today. But for various reasons, whether commercial or political, it hasn't happened yet. We are trying to look one by one at those obstacles to see where we can have an impact to make the Internet available to everyone.
