What is Google' s business strategy?

What did those Google guys say abouth their strategy?

(from time.com cover story: Meet the Google Guys)

IS THERE A GRAND STRATEGY FOR GOOGLE? IT SEEMS AS IF YOU'RE DIVING INTO ALMOST EVERYTHING.

SCHMIDT(CEO): We try very hard to look like we're out of control. But in fact the company is very measured. And that's part of our secret.

PAGE(Co-founder): We don't generally talk about our strategy ... because it's strategic. I would rather have people think we're confused than let our competitors know what we're going to do. That's an easy trade-off.

After its IPO and huge success from gaining advertisement revenues, Google now has abundant cash to do more in its R&D sector, so it seems they are currently penetrating into "almost everything".

In my point of view, Google is trying to evolve from just a search engine company to all-round electronic information service company which is driven by searching and advertising. They are doing so through the following two aspects:

Competing against existing companies with traditional services

Exploring new hot spot to expand its own business scope
