From Steve Jobs by Walter Isaacson
Steve Jobs recounts the advice he shared with Larry Page, Google’s co-founder and CEO:
We talked a lot about focus. And choosing people. How to know know who to trust, and how to build a team of lieutenants he can count on. I described the blocking and tackling he would have to do to keep the company from getting flabby or being larded with B players. The main thing I stressed was focus. Figure out what google wants to be when it grows up. It’s now all over the map. What are the five products you want to focus on? Get rid of the rest, because they’re dragging you down. They’re turning you into Microsoft. They’re causing you to turn out products that are adequate but not great.
Only some months later, in September 2011, Google stated that they will let go of some of their producs: http://googleblog.blogspot.com/2011/09/fall-spring-clean.html
