In brief
Google began as an academic project of two Stanford graduate students, not as a business: in a 1998 paper the authors wrote that search engines living on advertising would be inherently biased toward the advertisers. In its first years the company made money by selling its search to other companies' portals, and in October 2000 it launched advertising paid by impressions. Google introduced pay-per-click paid placement only in February 2002, while GoTo.com (the future Overture) had launched it as early as June 1, 1998. Overture filed suit in April 2002, and the case was closed by a settlement on August 9, 2004, ten days before the IPO: Google received a license to the patent and gave Yahoo 2.7 million shares for two disputes at once. Google's revenue for 2002 is $347.8 million in the first S-1 and $439.5 million in the August S-1/A: these are two ways of accounting for the same year.
How it started (the founders)
Larry Page and Sergey Brin met in 1995, when Brin was assigned to show the Stanford campus to a prospective graduate student. Page and his advisor decided to collect the links on the web; by Page's account, nobody was looking at the links, at which pages linked to which. The idea of ranking by links was set out in a patent application with a priority date of January 10, 1997; the patent was issued to Stanford University, not to Page personally. Brin came to it from the analysis of large data sets. The work was carried out by the Stanford Digital Library Project group with support from NSF, DARPA, and NASA; by the authors' own account, Scott Hassan and Alan Steremberg made a key contribution to the development, but they did not become co-founders of the company.
The company was incorporated in September 1998 (per secondary sources, on September 4), shortly after Andy Bechtolsheim's $100,000 check, written in August to a legal entity that did not yet exist. Until the end of 1998 the site lived on the university domain and belonged to Stanford.

Lesser-known but significant facts
- The founders' 1998 paper warned explicitly against the very model on which Google later grew rich. The authors expected that ad-funded search engines would be biased toward advertisers, and showed this with the query "cellular phone." A little over two years later Google began selling advertising.
- In 1999 GoTo.com and Google stood in the same list of Netscape search providers. Seven companies were equal "Premier Providers"; three years later one of them sued another.
- The first version of AdWords was not an auction. In October 2000 the price depended only on the position of the ad and was charged per impression; bids per click appeared in February 2002. The 2002 press release does not mention GoTo/Overture.
- The 2004 settlement closed two disputes, not one. Besides the patent, the parties were in dispute over Yahoo's warrant from the 2000 agreement; in June 2003 Google issued Yahoo 1,229,944 shares under the conversion terms, and Yahoo demanded more. For the two disputes Google gave up 2.7 million shares; in the S-1/A of 2004-08-18, the block is valued at $243 million at the midpoint of the IPO range ($90): $205 million (the midpoint of the $195–215 million estimate) goes to a one-time non-cash charge, and $38 million goes to intangible assets received under the settlement; in the version of 2004-08-09 (range $108–135), the charge was $260–290 million.
- 2002 revenue differs between the two versions of the S-1. The April S-1 shows $347.8 million, the August S-1/A $439.5 million; in the second, advertising revenue is presented gross, and payments to partners moved into cost of revenues. These are two methods of accounting, not the correction of an error.
Legend vs. the record
- Legend: Google invented paid search advertising. The record: according to GoTo.com's annual report for 1999, its pay-for-performance service was announced in February and officially launched on June 1, 1998; Slate's retelling dates the launch to February. In October 2000 Google sold impressions at a fixed price per position, and it introduced the pay-per-click model in February 2002. Google's own words in the prospectus: the company has only a short history with the "cost-per-click" model it launched in 2002. Verdict: false. What is true is narrower: Google added the ad's click-through rate to the bid in ranking; how far this changes the substance of Overture's invention was a question for the lawyers, and it was closed by a settlement with no court ruling on infringement.
- Legend: Google simply copied GoTo's auction. The record: Overture filed suit in April 2002 and claimed that AdWords infringed its patent on placement by bid; Google denied infringement and considered the patent invalid. The dispute ended with a license and shares, not a court ruling. Verdict: not provable from the documents; that Google worked from GoTo's model can be stated as a researcher's assumption, but not as a fact estimate.
- Legend: Google grew without spending money on marketing. The record: until mid-1999 the company reported that its growth of 50% a month came from word of mouth alone; this is the company's own statement and has not been independently verified. But as early as 1999 Google was built into Netscape, in 2000 into Yahoo, and in 2002 into AOL. For partners like these Google concluded agreements with guaranteed minimum payments; AOL, mainly through AdSense, accounted for about 15% of 2002 revenue. The $100 million AOL guarantee and the 85% share of advertising revenue for AOL turned up in only one secondary retelling estimate. Verdict: true until 1999 by the company's own account; after that, Google bought distribution.
- Legend: Google was against advertising and was born with the slogan "Don't be evil" at the IPO. The record: the 1998 paper did warn about advertising's conflict of interest, and advertising arrived in 2000. "Don't be evil," according to an investigation by Quote Investigator citing a Wayback snapshot, was on the company's site no later than March 27, 2002, before the IPO estimate, and in the founders' letter in the April 2004 S-1 it became a public formula. Verdict: half true; the internal date the phrase originated is disputed (2000, per Buchheit, or July 2001, per Levy's book) estimate.
The first growth lever
The first lever: Google became the search "backend" for other companies' portals with ready-made traffic, and its own advertising caught up later. Netscape in June 1999, Yahoo in June 2000, AOL in May 2002. By the time of the Yahoo deal Google was serving 76 sites in 20 countries. In 2003 the Yahoo agreement accounted for less than 3% of revenue, and AOL for about 15% in 2002; the company did not depend on one partner the way Overture did, with about 60% of its revenue coming through Microsoft and Yahoo.
The second lever was paid placement. Google's revenue grew from $86.4 million in 2001 to $347.8 million in 2002 (+302%) per the first S-1, and to $439.5 million in the S-1/A. This growth cannot be tied to AdWords Select alone: the AOL deal also took effect in 2002 estimate. AdSense's share of revenue grew from 24% in 2002 to about 50% in the first half of 2004.
The paired story
The pair: Google and Overture Services (GoTo.com). The story: who invented paid search and who made the money from it. One idea, selling places in search results for a pay-per-click bid, ended differently for the two companies.
- 1998. GoTo.com announces the sale of places by bid in February and launches it on June 1. That year Google incorporates and has no advertising.
- 1999. Both are on the same list of Netscape providers. Overture's patent application is filed in May 1999.
- 2000–2002. Google launches AdWords on impressions, then AdWords Select on clicks. Overture takes in $667.7 million in revenue in 2002, about 60% of it through Microsoft and Yahoo. The suit of April 23, 2002, comes 62 days after AdWords Select.
- 2003. Yahoo buys Overture for $1.63 billion and gets the lawsuit along with the company.
- 2004. The settlement on August 9: a license for Google, 2.7 million shares for Yahoo; the IPO on August 19.
The fork: the same model, a different outcome. At Overture the pay-per-click bid was a product that depended on two partners; at Google it was one source of income alongside a search engine that drew users on its own. How much of this difference is owed to ranking that factors in click-through rate, and how much to the size of Google's audience, the documents do not separate estimate.
Scale in 2002: Overture reported gross revenue of $667.7 million, and Google $439.5 million on the gross basis of the S-1/A, so Overture was roughly 1.5 times larger. In the Overture dossier: the GoTo launch, the patent, the revenue structure, the 2003 Yahoo deal.
Parallels today (projects from the catalog)
- Outbid.lol (
outbid-lol): a public board where the top spot goes to whoever paid more than the previous leader. The mechanism is the same as GoTo's, in its simplest form: a place for money, on the principle of a bid. The difference: at Google the order of ads was also determined by click-through rate, while on the board only the amount counts. view this project's dossier → - KDP Amazon Ads AI (
kdp-amazon-ads-ai-saas): automates the management of an author's advertising campaigns on Amazon. A direct descendant of auction-based advertising in search results: a paid position in the results is determined by the bid, and a whole industry of services lives on optimizing bids. The difference: Google in 2002 gave the advertiser self-service, while here an add-on sits on top of a ready-made auction marketplace. view this project's dossier → - Google Maps Rank Tracker AI Coach (

What a builder can take from this in 2026
- The best technology is not yet a business model. From 1999 Google sold search to portals, from 2000 advertising impressions, and it added pay-per-click paid placement in 2002, when others had already invented and patented it.
- Someone else's distribution channel does not replace your own. Netscape, Yahoo, and AOL gave Google an audience, but in these deals Google paid its partners guaranteed payments: the price of a channel is written into the contract, not only into growth.
- Before launching a product that resembles someone else's, check the competitor's patents. The suit came 62 days after the launch, dragged on for more than two years, and was closed ten days before the IPO.
- Dependence on two partners is more dangerous than someone else's model. At Overture about 60% of revenue went through Microsoft and Yahoo; at Google neither Yahoo nor AOL provided a share like that.
Discrepancies and what we could not verify
- The date of Overture's suit. MediaPost gives April 5, 2002, and Overture's 10-K April 23; the second is accepted, and it agrees with the S-1/A ("April 2002").
- 2002 revenue. $347.8 million (S-1) and $439.5 million (S-1/A) are different methods of accounting; Acquired Briefing gives $440 million without explanation.
- The terms of the AOL deal. The $100 million guarantee and 85% of revenue come from only one secondary source; the S-1/A does not disclose the amounts; snippets from eWeek say that Overture offered AOL more money estimate.
- Excite. Bell puts the price at $750,000 in cash plus about 1% of Excite, and gives the reason for the refusal as the demand to replace Excite's technology with Google's; he calls the version about a quality test nonsense. Khosla named prices of $1 million and $750,000, and Levy $1.6 million estimate.
- The 1998 angel investments. Bechtolsheim wrote a $100,000 check; per secondary sources, Bezos invested $250,000 estimate, and several others $250,000 each; these cannot be counted as the same amount, since Bechtolsheim's check is not equal to their investment.
- The incorporation date. The S-1 gives only September 1998; the 4th comes from secondary sources estimate.
- Stanford's stake. The university's earnings of $336 million on the shares come from secondary retellings estimate.
- Rumor: Google offered to buy GoTo for about $200 million. One secondary source rumor.
- Not verified: the terms of the 2000 agreement with Yahoo and the amount of the AOL payments, or a court ruling on the patent (there was none).
