There are 2 more nice videos on youtube (gooTube) worth watching:
There is a excellent book on search industry: The Search.
John Battelle’s, The Search: How Google and Its Rivals Rewrote the Rules of Business and Transformed Our Culture is the only book you need to read about the search industry in present day. John Battelle’s research is completely comprehensive and his style of writing is so easy to read you would never know you were reading about as complex a subject as the search industry. The book delves into the history of search and the monetization of search engine queries. The search also goes into depth about the present and future of search mainly revolving around Google’s role within the industry. The great thing about this piece of literature is that John Battelle does not take a side. He doesn’t write from the angle of being a Google supporter or a Google Hater. He takes a very neutral stance which makes is a much more enjoyable read. Mr. Battelle’s outlook on search becoming integrated with every facet of advertising is an opinion I have never read in the past but makes a lot of sense.
I have a small article which says: Don't be Too Evil
