Microsoft Internet Explorer 3 (Internet Explorer 3.0) is a graphical web browser released on August 13, 1996 by Microsoft for Microsoft Windows and on January 8, 1997 for Apple Mac OS (see IE for Mac). It kicked off serious competition against Netscape Navigator in the first Browser war.[3] It was the first more widely used version of Internet Explorer, although it did not surpass Netscape or become the browser with the most market share. During its tenure, IE market share went from roughly 3-9% in early 1996 to 20-30% by the end of 1997.[4][5][6][7] In September 1997 it was superseded by Microsoft Internet Explorer 4.
Internet Explorer 3 was the first major browser with CSS support. It also introduced support for ActiveX controls, Java applets, inline multimedia, and the Platform for Internet Content Selection (PICS) system for content metadata. Version 3 also came bundled with Internet Mail and News, NetMeeting, and an early version of the Windows Address Book, and was itself included with Windows 95 OSR 2. There were 16-bit and 32-bit versions depending on the OS.
IE3 was the first version developed without Spyglass source code, but still used Spyglass technology, so the Spyglass licensing information remained in the program's documentation. In 1996 Microsoft said of its new browser "Microsoft® Internet Explorer 3.0 adds many new features which are great for HTML authors and demonstrates our accelerating commitment to W3C HTML standards. " [8]

[edit] Overview
Internet Explorer 3.0 was released free of charge in August 1996 by bundling it with Windows 95 OSR2, another OEM release. Microsoft thus made no direct revenues on IE and was liable to pay Spyglass only the minimum quarterly fee. In 1997, Spyglass threatened Microsoft with a contractual audit, in response to which Microsoft settled for $8 million U.S.[9] Version 3 included Internet Mail and News 1.0 and the Windows Address Book. It also brought the browser much closer to the bar that had been set by Netscape, including the support of Netscape's plugins technology (NPAPI), ActiveX, frames, and a reverse-engineered version of JavaScript named JScript. Later, Microsoft NetMeeting and Windows Media Player were integrated into the product and thus helper applications became not as necessary as they once were. Cascading Style Sheets (CSS) were also introduced with version 3 of Internet Explorer. While IE1 and IE2 were said have "paled" in comparison to Netscape, IE3 "delivers a crushing blow to Netscape". [10] The user interface notably changes, with much larger buttons, with more intricate icons, and with a light grey design behind it . [11] Unlike later IE versions, users who upgraded to IE3, could still use the last IE by converting the previous version to separate directory. [12] It also could import favorites into IE3 from IE1 or 2. [13]The competition between Netscape and Microsoft heated up, with some saying the Internet community "became polarized on the issue of which web browser had the most features" [14] Other new features included Jscript, ActiveMovie multimedia API, HTML Layout Control, Quick Links toolbar, VRML, CSS [15] Microsoft announced on July 29, 1996 that it would develop a native version of IE for "Solaris and other popular variants of UNIX" to be available "by the end of 1996" which would have "equivalent functionality as that provided in Microsoft Internet Explorer 3.0", thus "delivering on its commitment to provide full-featured Web browser support on all major operating system platforms" as well as "supporting and promoting open standards, including HTML, ActiveX and Java".[16] In March, 1997 following a dispute which "arose between Microsoft and Bristol concerning each other’s performance of the 1996 IE Agreement"[17] and likely also because of contract negotiations with Bristol to access Windows source code after September 1997 failing,[18] Microsoft reversed course and decided to directly port the Windows version in-house using the MainWin XDE (eXtended Development Environment) application from Mainsoft,[19] the main competitor to Bristol Technology.[17] (Microsoft would later also use MainWin to port Windows Media Player and Outlook Express to Unix.[20]) Now well behind schedule, the 3.0 branch was apparently scrapped in favor of 4.0 (that was released for Windows half a year earlier), which used the new Trident rendering engine. A Internet Explorer 4 Beta for Solaris was released by the end of 1997,[21] leading to Internet Explorer for UNIX versions, which lasted until Internet Explorer 5.
[edit] Internet Explorer version 3.0 for Macintosh
Internet Explorer 3 for Macintosh was released on January 8, 1997 for PPC, and added support for the SSL and NTLM security protocols and the PICS and RSACi rating systems that can be used to control access to websites based on content ratings. On November 5, 1996 Microsoft announced the release of a beta version for Mac of Internet Explorer version 3.0. This release added support for HTML version 3.2, Cascading Style Sheets [22], Java applets and ActiveX controls. Keith Mitchell of Macworld noted in November 1996, when discussing the IE mac version, "With the near-simultaneous release of Netscape Navigator 3.0 (415/528-2555, http://www.netscape.com ) and Microsoft Internet Explorer 3.0 (206/882-8080, http://www.microsoft.com ), both companies are tripping over each other to entice Web users to their products." [23] A problem with an operating system extension used in the Mac OS called CFM68K Runtime Enabler, led to a delay in the release of the version 3.0 for Macs based on the 68k line of processors. Four months later on May 14, Microsoft released version 3.01 which included a version for 68k-based machines. This version also included features from the Windows version of Internet Explorer 4.0 such as AutoComplete and Monitoring Favorites that notified users when sites in their Favorites list have been updated. It also included support for JavaScript and introduced a Download Manager and a Cookie Manager. MacUser's review noted "While Netscape Navigator 3.0 is more feature-laden and consequently bigger and slower than previous incarnations, Microsoft Internet Explorer has been refined and optimised into a Web browser that has almost as many features, but is both smaller and faster than its rival." [24]
[edit] Bundled and/or integrated software
IE3 launched with a variety of integrated apps, with some added later. [25]
- Internet Mail and News an e-mail and news client included with IE3. It was replaced/renamed in IE4 as Outlook Express 4.0.
- Windows Address Book an application that has a local database and user interface that lets users keep a single list of contacts that can be shared by multiple programs. It can query LDAP servers or read/write data to a local .wab file. Later versions were no longer bundled with IE, instead with Windows until Vista.
- Microsoft Comic Chat is a text chatting program that used cartoon avatars to display text and emotion. It was replaced by Microsoft Chat in IE4.
- Real Player was a streaming media player made by Progressive Networks (later called RealNetworks). The first version of RealPlayer was introduced in April 1995 as RealAudio Player and was one of the first media players capable of streaming media over the Internet.[26] Versions 3.0.1 for Windows 3.11 - RealPlayer 2.1.1.10, 3.0.2 for Windows 95 - RealPlayer 2.1.1.9, and 3.0.2 for Windows NT - RealPlayer 2.1.1.9.
Later versions of Internet Explorer 3 also included:
- Microsoft NetMeeting is a VoIP and multi-point videoconferencing client that uses the H.323 protocol for video and audio conferencing.
- Windows Media Player an audio and visual media player playing several formats including .avi. The browser could play MIDI files on its own. [27]
IE3 also included Microsoft Java Virtual Machine, which continued to be included until 5.5 when due to legal battle between Sun and Microsoft, it had to be removed from the product. However, it was supported for several years after this.
[edit] Adoption capability overview
Internet Explorer 3.0 had support for Windows 3.1, Windows 95, Windows NT 3.51[28], and Windows NT 4.0. Version 3.0 was included in Windows 95 OSR2, but Windows 98 launched with IE4. Major MS OS releases after Win 98, switched to supporting Internet Explorer 4 (or higher). Internet Explorer 3 had a Beta supporting Solaris (UNIX). IE4 integration with the OS meant systems that upgraded from IE3 to 4, or came with 4, could not easily revert to IE3 (see Removal of Internet Explorer. The Mac OS version supported PPC and 68k Macs, superseding IE 2.1. Microsoft released various 16- and 32-bit versions for Windows.
[edit] Encryption
The last patch versions of Internet Explorer 3 supported 40-bit and 128-bit encryption, using Server Gated Cryptography (SGC). [29] 256-bit encryption would not become available in IE for nearly 10 years with, the Windows Vista version Internet Explorer 7.
128-bit encryption was available or included for these versions:[30]
- Microsoft Internet Explorer 3.03 for Windows NT 3.51 SP 1
- Microsoft Internet Explorer 3.02
- Microsoft Internet Explorer 3.0 for Macintosh
If it was not possible to upgrade to 128-bit, then 40-bit (SGC) was standard.[31]

[edit] Extended
Shdocvw.dll version numbers plus related notes.[32] Unlike later versions, early IE version numbers were numerically out of sync with the .dll numbers because they were based of the Windows version numbers (due to its beginnings in the Microsoft Plus! pack, which also based of the Windows number). IE 1 started with 4.4 because Windows 95 was version 4 of MS Windows.
- major version.minor version.build number.sub-build number
- 4.70.1155 Internet Explorer 3.0
- 4.70.1158 Internet Explorer 3.0 (Windows 95 OSR2)
