Google has won both the online search and advertising markets. They hold a considerable technological lead, both with algorithms as well as their astonishing web-scale computing platform.

To paraphrase an old comment about IBM, made during its 30 year dominance of the enterprise mainframe market, Google is not your competition, Google is the environment.
