How is google founded

At the time Page conceived of BackRub, the Web comprised an estimated 10 million documents, with an untold number of links between them. The computing resources required to crawl such a beast were well beyond the usual bounds of a student project. Unaware of exactly what he was getting into, Page began building out his crawler. The idea's complexity and scale lured Brin to the job. A polymath who had jumped from project to project without settling on a thesis topic, he found the premise behind BackRub fascinating.

In March , Page pointed his crawler at just one page - his homepage at Stanford - and let it loose. The crawler worked outward from there. Crawling the entire Web to discover the sum of its links is a major undertaking, but simple crawling was not where BackRub's true innovation lay. Page was naturally aware of the concept of ranking in academic publishing, and he theorized that the structure of the Web's graph would reveal not just who was linking to whom, but more critically, the importance of who linked to whom, based on various attributes of the site that was doing the linking.

Inspired by citation analysis, Page realized that a raw count of links to a page would be a useful guide to that page's rank.

He also saw that each link needed its own ranking, based on the link count of its originating page. But such an approach creates a difficult and recursive mathematical challenge - you not only have to count a particular page's links, you also have to count the links attached to the links. The math gets complicated rather quickly. Fortunately, Page was now working with Brin, whose prodigious gifts in mathematics could be applied to the problem.

By the time he was a middle schooler, Brin was a recognized math prodigy. He left high school a year early to go to UM. When he graduated, he immediately enrolled at Stanford, where his talents allowed him to goof off. The weather was so good, he told me, that he loaded up on nonacademic classes - sailing, swimming, scuba diving.

He focused his intellectual energies on interesting projects rather than actual course work. Together, Page and Brin created a ranking system that rewarded links that came from sources that were important and penalized those that did not. For example, many sites link to IBM. Those links might range from a business partner in the technology industry to a teenage programmer in suburban Illinois who just got a ThinkPad for Christmas.

To a human observer, the business partner is a more important link in terms of IBM's place in the world. But how might an algorithm understand that fact? Page and Brin's breakthrough was to create an algorithm - dubbed PageRank after Page - that manages to take into account both the number of links into a particular site and the number of links into each of the linking sites. This mirrored the rough approach of academic citation-counting.

It worked. In the example above, let's assume that only a few sites linked to the teenager's site. Let's further assume the sites that link to the teenager's are similarly bereft of links. By contrast, thousands of sites link to Intel, and those sites, on average, also have thousands of sites linking to them.

This is a simplified view, to be sure, and Page and Brin had to correct for any number of mathematical culs-de-sac, but the long and the short of it was this: More popular sites rose to the top of their annotation list, and less popular sites fell toward the bottom. As they fiddled with the results, Brin and Page realized their data might have implications for Internet search. In fact, the idea of applying BackRub's ranked page results to search was so natural that it didn't even occur to them that they had made the leap.

As it was, BackRub already worked like a search engine - you gave it a URL, and it gave you a list of backlinks ranked by importance. Page and Brin noticed that BackRub's results were superior to those from existing search engines like AltaVista and Excite, which often returned irrelevant listings. Page and Brin encountered many problems in trying to get Google of it's feet.

Finding the right investors wasn't as easy as it may seem, especially at that time. Page and Sergey did manade to get an investor, Andy Bechtolshei. Andy took one quick look at the Google Demo, and immediately wrote Larry and Sergey a check for ,, made out to Google Inc.
