-"We believe the issue of advertising causes enough mixed incentives that it is crucial to have a competitive search engine that is transparent and in the academic realm. "
- "We expect that advertising funded search engines will be inherently biased towards the advertisers and away from the needs of the consumers."
- "A better search engine would not have required this ad, and possibly resulted in the loss of the revenue from the airline to the search engine. In general, it could be argued from the consumer point of view that the better the search engine is, the fewer advertisements will be needed for the consumer to find what they want. This of course erodes the advertising supported business model of the existing search engines."
To be clear: the "we" in these quotes are the founders of Google.

As an aside, I've been reading a bunch of academic papers about early web crawlers and search engines. It's a fun and interesting subject. Mercator [2] (which became Alta Vista) is another early search engine and one of the few that discusses its architecture in detail.
