In the early 1990s, U.S. academic networks were still governed by rules that limited many kinds of business use. Policy shifts by the National Science Foundation (NSF) began loosening these limits, creating space for commercial Internet service providers (ISPs) and business traffic to grow alongside research and education uses.
In mid-1991, PSINet, UUNET, and CERFnet helped organize the Commercial Internet eXchange (CIX). CIX mattered because it offered a way for networks to exchange traffic—including commercial traffic—without a government-defined acceptable-use policy, pointing toward the later “public” commercial Internet.
NCSA Mosaic’s early 1993 release helped many more people use the World Wide Web. It improved ease of use and popularized web navigation for non-specialists, helping shift the Internet from mainly technical and academic use toward broader public adoption.
Jeff Bezos founded Amazon on July 5, 1994, initially as a business focused on selling books online. Its founding became an early signal that the Web could support consumer retail at national scale, not just information sharing.
Netscape Navigator’s release helped turn the Web into a practical platform for everyday users and businesses. Browser competition and rapid improvements made it easier for companies to reach customers online, supporting the growth of web-based commerce and advertising.
On April 30, 1995, the NSFNET Backbone Service was shut down as the U.S. Internet transitioned to an architecture based on multiple competing backbones linked at new interconnection points. This was a major turning point because it marked the end of a primary government-sponsored backbone and the rise of a more fully commercial Internet infrastructure.
Amazon’s website opened for public sales in mid-1995, bringing a large online catalog to ordinary consumers. It showed how web-based ordering could work at scale, encouraging other retailers and startups to try online sales models.
On August 9, 1995, Netscape’s initial public offering (IPO) drew major attention and strong trading on its first day. The IPO helped convince investors that Internet companies could grow quickly, encouraging more venture funding and public-market interest in web businesses.
Pierre Omidyar launched AuctionWeb on September 3, 1995, which later became eBay. The site helped popularize person-to-person online marketplaces, showing that trust mechanisms and user listings could support large volumes of commerce online.
President Bill Clinton signed the Telecommunications Act of 1996 on February 8, 1996, updating U.S. communications law and aiming to promote competition and reduce regulation. The broader policy climate supported expanding private investment in networks that carried Internet traffic, including broadband and related services.
Amazon’s IPO on May 15, 1997, raised capital for expansion and increased investor attention on online retail. It also reinforced a pattern of Internet companies using public markets to fund rapid growth, even before reaching sustained profitability.
On September 24, 1998, eBay went public and its share price rose sharply on the first day of trading. The IPO strengthened the idea that online marketplaces could become durable businesses, further fueling investor interest in e-commerce models.
The Internet Tax Freedom Act was signed into law on October 21, 1998, creating a moratorium on certain state and local taxes targeting Internet access and electronic commerce. This helped reduce uncertainty for businesses building online services and for consumers paying for Internet access.
On January 10, 2000, AOL announced it would merge with Time Warner in a deal promoted as combining Internet distribution with major media content. The announcement became a symbol of dot-com era optimism about Internet platforms reshaping established industries.
On March 10, 2000, the NASDAQ Composite hit its intraday peak of 5,132.52 and closed at 5,048.62, widely treated as the high-water mark of the dot-com era. This peak reflected extreme expectations for Internet company growth and set the stage for a sharp market reversal.
After early 2000, many Internet companies ran out of cash or could not justify their valuations, leading to layoffs, bankruptcies, and major losses for investors. The crash forced surviving firms to focus on sustainable revenue and realistic business models, shaping the next phase of U.S. e-commerce and commercial platforms.
