Our goal is long-term growth in revenue and absolute profit - so we invest aggressively in future innovation while tightly managing our short-term costs.

I have always believed that technology should do the hard work - discovery, organization, communication - so users can do what makes them happiest: living and loving, not messing with annoying computers! That means making our products work together seamlessly.

We understand the need to balance our short- and longer-term needs because our revenue is the engine that funds all our innovation. But over time, our emerging high-usage products will likely generate significant new revenue streams for Google as well as for our partners, just as search does today.

Excellence matters, and technology advances so fast that the potential for improvement is tremendous. So, since becoming CEO again, I've pushed hard to increase our velocity, improve our execution, and focus on the big bets that will make a difference in the world.

Most of us carry at least one device, all the time, every day. In fact many of us would feel naked without our smartphone. It's hardly surprising mobile search queries - and mobile commerce - are growing dramatically across the world.

Artificial intelligence would be the ultimate version of Google. The ultimate search engine that would understand everything on the Web. It would understand exactly what you wanted, and it would give you the right thing. We're nowhere near doing that now. However, we can get incrementally closer to that, and that is basically what we work on.

You may think using Google's great, but I still think it's terrible.
