Nonsense. When Google went online, there established players then just as there are established players today. Ever heard of Alta Vista, Lycos, HotBot, Webcrawler, Ask Jives, and many, many others--both non-commercial and commercial? Google rose to the top because it was the best available, not because it was on the scene first--because it was not.
Excuse me? I said absolutely nothing regarding "why Google rose to the top".
What I did address however was your naive contention that "developing a search engine is a very inexpensive proposition". It isn't. And anyone who thinks indexing something on the order of 10 billion Web pages would be an "inexpensive" undertaking hasn't a clue regarding the enormity of such a project.
In regards to " Alta Vista, Lycos, HotBot, Webcrawler, Ask Jives" and such -- yes, I've "heard of them". Since I was using the Net before they existed I also remember using them when they were all brand new.
