Beginnings – Google has its origins in “BackRub”, a research project that was begun in 1996 by Larry Page and Sergey Brin when they were both PhD students at Stanford University in Stanford, California, The project initially involved an unofficial “third founder”, Scott Hassan, the lead programmer who wrote much of the code for the original Google Search engine, but he left before Google was officially founded as a company; Hassan went on to pursue a career in robotics and founded the company Willow Garage in 2006.
- In the search of a dissertation theme, Page had been considering among other things exploring the mathematical properties of the World Wide Web, understanding its link structure as a huge graph,
- His supervisor, Terry Winograd, encouraged him to pick this idea (which Page later recalled as “the best advice I ever got” ) and Page focused on the problem of finding out which web pages link to a given page, based on the consideration that the number and nature of such backlinks was valuable information about that page (with the role of citations in academic publishing in mind).
Page told his ideas to Hassan, who began writing the code to implement Page’s ideas. The research project was nicknamed “BackRub”, and it was soon joined by Brin, who was supported by a National Science Foundation Graduate Fellowship, The two had first met in the summer of 1995, when Page was part of a group of potential new students that Brin had volunteered to give a tour around the campus and nearby San Francisco.
- Both Brin and Page were working on the Stanford Digital Library Project (SDLP).
- The SDLP’s goal was “to develop the enabling technologies for a single, integrated and universal digital library” and it was funded through the National Science Foundation, among other federal agencies.
- Brin and Page were also part of a computer science research team at Stanford University that received funding from Massive Digital Data Systems (MDDS), a program managed for the Central Intelligence Agency (CIA) and the National Security Agency (NSA) by large intelligence and military contractors.
Page’s web crawler began exploring the web in March 1996, with Page’s own Stanford home page serving as the only starting point. To convert the backlink data that is gathered for a given web page into a measure of importance, Brin and Page developed the PageRank algorithm.
While analyzing BackRub’s output which, for a given URL, consisted of a list of backlinks ranked by importance, the pair realized that a search engine based on PageRank would produce better results than existing techniques (existing search engines at the time essentially ranked results according to how many times the search term appeared on a page).
Convinced that the pages with the most links to them from other highly relevant Web pages must be the most relevant pages associated with the search, Page and Brin tested their thesis as part of their studies and laid the foundation for their search engine.
- The first version of Google was released in August 1996 on the Stanford website.
- It used nearly half of Stanford’s entire network bandwidth.
- Some Rough Statistics (from August 29, 1996) Total indexable HTML urls: 75.2306 Million Total content downloaded: 207.022 gigabytes,
- BackRub is written in Java and Python and runs on several Sun Ultras and Intel Pentiums running Linux.
The primary database is kept on a Sun Ultra II with 28GB of disk. Scott Hassan and Alan Steremberg have provided a great deal of very talented implementation help. Sergey Brin has also been very involved and deserves many thanks. Scott Hassan and Alan Steremberg were cited by Page and Brin as being critical to the development of Google.
- Rajeev Motwani and Terry Winograd later co-authored with Page and Brin the first paper about the project, describing PageRank and the initial prototype of the Google search engine, published in 1998.
- Héctor García-Molina and Jeff Ullman were also cited as contributors to the project.
- PageRank was influenced by a similar page-ranking and site-scoring algorithm earlier used for RankDex, developed by Robin Li in 1996.
Larry Page’s patent for PageRank filed in 1998 includes a citation to Li’s earlier patent. Li later went on to create the Chinese search engine Baidu in 2000.
