Internet Explorer

1995

Internet Explorer wasn’t a browser — it was a distribution mechanism disguised as software.

Internet Explorer was a Windows-only graphical web browser first released in 1995 as part of the Plus! add-on for Windows 95. It used the Trident engine from version 4 (September 1997). Feature development ended after 2015. Official support ended on June 15, 2022, for Windows 10 SAC editions. Microsoft Edge succeeded it as Microsoft's primary browser. The core of IE 11 continues as IE Mode in Edge until at least 2029.

    Bundled, not built

    It launched not as standalone software, but as part of Windows 95’s Plus! add-on package.

    The engine that locked it in

    Trident arrived with IE 4 in September 1997 — the engine that defined its rendering behaviour for the next two decades.

    Retired, not replaced

    Feature development ended after 2015. Support died on June 15, 2022 — for Windows 10 SAC editions.

    Zombie architecture

    Its core lives on only as IE Mode in Microsoft Edge — a compatibility mode, not a browser.

  5. 5:41
    Successor with a ghost inside

    It was a series of Windows-only browsers. Microsoft Edge succeeded it as the primary browser — but IE’s code still ships inside Edge.

Worth your time?

No. The brief is enough.

The written brief1 min read

What it is and the problem it solves

A Windows-only graphical web browser. It solved the problem of giving Windows 95 users immediate, integrated access to the early web — without requiring separate installation or technical setup.

How it works

Internet Explorer was a graphical web browser embedded in Windows. It launched as part of the Plus! add-on for Windows 95. It relied on bundled OS integration to distribute and update itself. From version 4, it used the Trident rendering engine.

What works

IE Mode in Microsoft Edge works. It renders legacy intranet pages built for IE 11’s Trident engine. That core remains supported until at least 2029 — but only as a backward-compatibility layer, not as an independent product.

What does not

It does not render modern web standards reliably. It does not support contemporary security protocols or developer tooling. It does not run outside Windows. It does not receive new features or meaningful updates.

What it changes

It changed how Windows users accessed the web — by making browsing inseparable from the OS. It entrenched platform lock-in. It shifted browser competition from interoperability to bundling and default status.

Is it worth your time

No. It is retired. Feature development stopped after 2015. Official support ended on June 15, 2022, for Windows 10 SAC editions. Its only remaining function is IE Mode inside Microsoft Edge — a compatibility shim, not a browser.

Amazon KindleThe Kindle is a proprietary e-reader platform built around E Ink hardware and Amazon’s closed content store. It delivers portability and battery life at the cost of format lock-in and limited interoperability. Its success rests on vertical integration—not innovation in display or typography.

Apple II1977The Apple II was a finished 8-bit microcomputer built around the 6502 processor, introduced on June 10, 1977. Designed by Steve Wozniak, it advanced beyond the Apple I in ease of use, features, and expandability. It became widely used in American secondary schools through volume discounts and institutional manufacturing arrangements. VisiCalc’s 1979 release drove adoption among business users and families. It supported text and two colour graphics resolutions, and delivered low-fidelity audio via a software-controlled speaker.

Apple Watch2015The Apple Watch (2015) is a wrist-worn extension of the iPhone, built for health tracking, notifications, and voice communication. It requires an iPhone for setup and sync but supports independent Wi-Fi and cellular connectivity on higher-tier models. Apple’s API restrictions prevent competing smartwatches from achieving equivalent iPhone integration—making the Apple Watch the only fully supported option. It sold 4.2 million units in its first fiscal quarter and became the world’s best-selling wearable device immediately upon release. As of September 2025, new units ship with watchOS 26 and require an iPhone 11 or later running iOS 26.

Chevrolet BoltGeneral MotorsThe Chevrolet Bolt EV redefined the mass-market electric vehicle by delivering over 200 miles of range at a $30,000 post-incentive price—verified in production by October 2016. Its development relied on LG for battery and drivetrain, GM for final assembly in Lake Orion, and Israeli engineers for the user interface. Prototype testing covered five key domains. But the sources say nothing about real-world durability, software evolution, charging speed, or cost of ownership.

Iridium isn’t rare because it’s special — it’s special because it’s rare, and that rarity locks its utility into three narrow, high-stakes industrial niches.
