Microsoft gave AOL visibility in Windows and technical help integrating a browser; AOL made Internet Explorer the standard built-in browser for its main service and helped promote it. The agreement was a strategic distribution and technology deal—not a merger—and it let two competitors cooperate without ending their rivalry.
Why rivals made a deal
In 1995, Microsoft and AOL were competing for customers. Microsoft launched MSN, or The Microsoft Network, alongside Windows 95 on August 24, intending it to compete with AOL and other online services. But Microsoft had a larger and more immediate concern: Netscape Navigator was gaining ground as the browser people used to explore the Web.

Windows gave Microsoft influence over what PC users saw and used, but AOL had its own powerful distribution channel: its subscriber base and software. Microsoft saw an agreement with AOL as a way to put Internet Explorer in front of millions of users. AOL, in turn, wanted a prominent place on Windows desktops and help building a better browser experience into its client software. The U.S. Department of Justice later described AOL as both an important internet-access provider and one of MSN’s fiercest competitors (DOJ memorandum supporting a preliminary injunction).
Microsoft’s own account of 1996 lists the AOL partnership among the year’s major developments (Microsoft’s 1996 company history). The deal made strategic sense precisely because the companies remained rivals: Microsoft could use AOL’s reach to advance Internet Explorer, while AOL could use Microsoft’s platform and support to strengthen its service.

How the negotiations took shape
Windows placement changed Microsoft’s calculation
In late 1995 and early 1996, Microsoft employees examined new PCs from major manufacturers, including Compaq, Hewlett-Packard, IBM, Packard Bell, and NEC. They found AOL software preinstalled or prominently displayed on some machines. That showed Microsoft that AOL already had a foothold in the Windows distribution channel. Rather than simply trying to push AOL out in favor of MSN, Microsoft could negotiate over AOL’s Windows presence—and seek a commitment on browsers in return. The DOJ’s findings of fact describe that examination and the negotiations that followed.
AOL was weighing more than one technology partner
AOL chairman and CEO Steve Case visited Microsoft’s Redmond campus in January 1996 as the companies began discussions. Negotiations continued through February and early March, while AOL also talked with Netscape and Sun about technology. The contemporaneous March 12 announcement-call transcript records AOL’s explanation that it was evaluating several technologies; the outcome was not simply a case of negotiations with Netscape failing before Microsoft stepped in.
GNN and AOL made different browser choices
On March 11, AOL announced Netscape Navigator as the primary browser for GNN, its smaller basic internet-service offering. The next day, it announced Internet Explorer as the standard built-in browser for its flagship AOL service. Netscape remained available to AOL customers as an option, according to the announcement-call transcript. AOL therefore chose different arrangements for different services rather than adopting Internet Explorer across every brand.
What the March 12, 1996 agreement exchanged
The companies announced their strategic partnership on March 12, 1996. Microsoft said AOL had more than five million customers at the time. The public announcement described joint marketing, cooperative engineering, AOL software for Windows 95, Windows 3.1, and Macintosh, and easy access to AOL from an Online Services folder on the Windows 95 desktop. It also said Internet Explorer would be integrated into AOL’s software (Microsoft’s announcement).

The table combines the public announcement with technical and commercial details recorded in the DOJ’s findings of fact. The public language emphasized cooperation and consumer access; the legal record shows that Windows placement and browser promotion were also part of the bargain.
What each company hoped to gain—and risked
Microsoft wanted browser distribution beyond its own reach
Microsoft could promote Internet Explorer through Windows, but an agreement with AOL offered a route into a major internet-access provider’s service and software. AOL’s user base could help Microsoft build Internet Explorer’s installed base and usage, making it a stronger competitor to Netscape Navigator. The DOJ record describes Microsoft treating AOL as a potential breakthrough because of its subscribers and importance as an access channel.
Giving AOL favorable Windows placement also meant making room for a direct competitor to MSN. Microsoft accepted that cost because its browser objective was more urgent than keeping AOL away from Windows. The alliance helped Microsoft pursue its browser strategy without first having to make MSN the more compelling service.
AOL wanted reach and help, while preserving room to maneuver
For AOL, visibility on the dominant PC operating system could help attract new users. Microsoft’s source-code access and engineering support could also make browser integration more practical. AOL had reasons to be cautious: Microsoft ran a competing service, and reliance on Microsoft technology could limit AOL’s independence. Its parallel work with Netscape and Sun, along with the separate GNN decision, shows that AOL did not put every part of its business behind one browser arrangement.

The DOJ’s proposed findings quote AOL president Bob Pittman explaining the importance of maintaining a relationship with Microsoft because Microsoft could harm AOL if it had no reason to cooperate (DOJ proposed findings, Section VII). For AOL, the deal was a calculated trade: accept browser-promotion terms and gain Windows access and technical assistance.

How later payments encouraged existing subscribers to switch
The March agreement addressed the browser in AOL’s software; a separate Promotional Services Agreement, signed October 28, 1996, was designed to encourage existing subscribers to upgrade. The DOJ’s account of that agreement lists these terms:
- Microsoft paid AOL $500,000 initially.
- AOL could earn $0.25 for each existing subscriber who upgraded to AOL software containing Internet Explorer, up to $1 million under that provision.
- AOL could earn a separate $600,000 milestone payment if it upgraded 5.25 million subscribers by April 1997.
- A separate referral arrangement gave AOL a $2 credit for each new subscriber who used Internet Explorer.
These figures come from the DOJ’s findings of fact about the October agreement, not from the simpler terms in Microsoft’s March public announcement. They show that AOL’s role developed beyond bundling: Microsoft also had financial incentives tied to upgrades and referrals.

The U.S. government examined the agreement as part of its antitrust case against Microsoft. Its concern was that Microsoft could use Windows’ value to influence adjacent markets, including browsers, by offering access to the desktop in exchange for favorable treatment of Internet Explorer. The DOJ’s findings describe the AOL arrangement as an exchange of Windows placement and other consideration for distribution and promotion of Internet Explorer to the near exclusion of Navigator. Its preliminary-injunction memorandum likewise presented desktop access as part of the bargain.
The AOL agreement was one example in a broader strategy, not a complete explanation of Internet Explorer’s gains or the entire basis of the case. Microsoft also made arrangements with services including AT&T WorldNet, Prodigy, and CompuServe, alongside other browser-distribution practices examined by the government. The legal record’s description of near-exclusivity should not be simplified into a claim that every AOL customer was forced to use Internet Explorer: Netscape remained an option in some contexts, and GNN selected Navigator as its primary browser.
Why AOL kept working with Microsoft after buying Netscape
In November 1998, AOL announced an acquisition of Netscape in a stock transaction valued at approximately $4.3 billion, according to the DOJ’s findings of fact. AOL nevertheless did not immediately exercise its contractual opportunity to terminate the Microsoft agreement’s exclusivity provisions at the end of 1998.
That decision makes sense if the agreement is viewed as a commercial calculation rather than an alliance built on loyalty. AOL still valued Windows distribution; it could own Netscape while continuing to use Internet Explorer in its main client; and Netscape offered assets beyond its browser, including its brand, portal, traffic, employees, and e-commerce operations. Keeping the Microsoft relationship also helped AOL preserve access to the Windows channel. The DOJ’s proposed findings discuss the continuing value AOL placed on Windows placement after acquiring Netscape.
The two companies’ interests could therefore align in one area and conflict in another. Microsoft gained a route for Internet Explorer; AOL retained a relationship with the Windows gatekeeper while owning a potential alternative in Netscape. The arrangement was flexible cooperation between competitors, not a permanent pact against Netscape.
The relationship continued in a different form
On May 28, 2003, AOL Time Warner and Microsoft announced a digital-media collaboration and settlement of pending litigation. The agreement included a long-term, nonexclusive license for AOL Time Warner to use Windows Media 9 technology and future Microsoft software for creating, distributing, and playing digital media. This was a later phase of cooperation, distinct from the 1996 browser-distribution deal (Microsoft’s 2003 announcement).
What brought Microsoft and AOL together
Microsoft and AOL came together because Windows access and AOL’s subscriber reach were valuable to each other at a moment when control of browser distribution mattered. Microsoft traded a place for AOL in Windows and technical support for AOL’s help making Internet Explorer the standard browser in its main service. The partnership did not erase their competition over online services, and it did not make AOL abandon Netscape everywhere. It was a pragmatic agreement whose benefits—and tensions—lasted beyond the original browser bargain.
