According to the rapid development of Google these years, I have to believe that Google will dominate internet marketing. Google begin to generate tons of dollars after they launched their advertising networks: Google Adwords and Google Adsense. They meet both advertisers and publishers. This is why they are so successful.
Recently Google begin to optimize their search engine technology and it is more and more scientific and user friendly. This proves that Google have a long sight.
So I believe Google will be the best at internet marketing in the near future. Of course I also hope I can earn a cake from Google.
