Dying Technologies

How Web Technologies Become Obsolete

In the web world, technologies die when something better comes along and reaches critical mass. It's not about technical superiority alone—it's about adoption, ecosystem, and momentum.

A technology can be obsolete but still in use. Internet Explorer is deprecated but still used on corporate intranets. FTP is dead but still works. WordPress 3.0 is ancient but still runs. So "dying" means it's no longer recommended for new projects, even if legacy systems still use it.

The pattern is consistent: technologies die when they have fundamental limitations, when open alternatives emerge, and when the industry achieves consensus that the alternative is better. Let's look at technologies that shaped the web and are now dying or dead.

Flash: The Plugin That Ruled and Fell

Flash was the dominant technology for rich media on the web from the late 1990s through the 2000s. You needed it for video playback, interactive content, and animations. At its peak, 99% of browsers had Flash installed.

Flash was powerful but had fatal flaws:

• Plugin requirement: You had to install Flash separately. Not everyone did.
• Performance: Flash was slow and CPU-intensive, especially on older computers.
• Mobile: Flash didn't work on iPhones or Android devices, a fatal blow as mobile traffic grew.
• Battery drain: Flash videos drained laptop batteries quickly.
• Security: Flash was frequently exploited by malware. It became a security nightmare.
• Proprietary: Flash was owned by Adobe. Standards-based alternatives were preferable.

HTML5 provided open alternatives: video and audio elements, canvas for drawing, and JavaScript APIs for interactivity. CSS3 added transforms and animations. Together, they provided most of what Flash could do without the overhead.

YouTube switched from Flash to HTML5 video in 2015. Other platforms followed. By 2020, Flash was essentially dead. Adobe officially discontinued Flash Player on December 31, 2020.

Flash's collapse teaches an important lesson: proprietary technologies lose to open standards, especially when the standards can provide similar capabilities.

Table Layouts: HTML Abused for Design

Before CSS was reliable, the only way to create multi-column layouts was to abuse HTML tables. You'd nest tables inside tables, add invisible spacer GIFs to control sizing, and hack every pixel into place.

Table layouts were terrible for many reasons:

• Semantically wrong: Tables are for data, not layout. Screen readers interpret tables as data and read them line-by-line, making them unusable for navigation.
• Bloated HTML: Table-based layouts required tons of nested markup, making HTML files large.
• Hard to maintain: Changing a layout meant rewriting dozens of cells.
• Bad performance: Browsers had to parse nested tables before rendering, making pages slow.
• Not responsive: Table layouts didn't adapt to different screen sizes.

By the mid-2000s, CSS became reliable enough to handle layouts. Developers moved to CSS-based layouts (using floats initially, then Flexbox and Grid). Table layouts became a sign of amateur web development.

You'll occasionally encounter table layouts in old codebases or from developers who learned on outdated tutorials. They're relics. Modern CSS (Flexbox, Grid) handles layouts far better.

FTP Deployment: Manual, Insecure, Outdated

For decades, deploying a website meant using FTP (File Transfer Protocol) to upload files to a server. You'd have an FTP client like FileZilla, you'd log in with a username and password, you'd drag files to the server.

FTP deployment had serious problems:

• Insecurity: FTP sends credentials in plaintext. Anyone sniffing the network can steal your password.
• Manual: FTP deployment is manual and error-prone. You might forget to upload a file or upload the wrong version.
• No history: FTP doesn't track changes. You don't know who deployed what or when.
• No rollback: If you deploy a broken version, rolling back requires manually re-uploading old files.
• No automation: You can't automatically test before deployment or run deployment scripts.

Modern deployment uses Git and CI/CD (continuous integration/continuous deployment). You commit code to GitHub, automated tests run, and if they pass, the code is automatically deployed. There's a full history of changes, permissions control, and rollback capability.

FTP is still technically possible and still used by some old hosting providers, but it's completely outdated. Modern web hosting uses Git-based deployment or API-based deployment. FTP belongs in a museum.

Internet Explorer: The Browser That Wouldn't Die

Internet Explorer dominated the browser market from 2000 to 2010 (80-95% market share) because it came bundled with Windows. Developers were forced to support IE despite its terrible standards compliance.

IE was a nightmare for web developers:

• Standards non-compliance: IE implemented web standards incorrectly or not at all. CSS worked differently in IE.
• Slow: IE was slow compared to competing browsers.
• Security vulnerabilities: IE was frequently compromised. Internet Explorer became synonymous with malware.
• Compatibility modes: IE added "compatibility modes" where it tried to emulate earlier IE versions, creating more confusion.
• No developer tools: IE's developer tools were primitive compared to Firefox and Chrome.

Firefox (2004) and Chrome (2008) provided faster, more standards-compliant alternatives. By 2015, IE market share had dropped below 10%. By 2022, Microsoft officially ended IE support, retiring it completely.

Microsoft replaced IE with Edge, a Chromium-based browser (2020). IE is now completely dead. Some legacy corporate systems still use it (running IE in compatibility mode on Windows 10), but no one should build new websites for IE.

The IE era was marked by frustration and workarounds. Modern web development is vastly better because we're no longer fighting IE's quirks.

jQuery: The Framework That Made JavaScript Bearable

jQuery (2006) was revolutionary. It abstracted away browser differences and made DOM manipulation easy. Before jQuery, you had to write verbose code with compatibility checks. jQuery did it in one line.

For a decade, jQuery was essential to web development. Every website used it. But jQuery became less necessary as:

• Modern JavaScript improved: ES6 (2015) made JavaScript much better. Modern JavaScript APIs are more powerful than jQuery.
• Browsers standardized: All modern browsers implement web standards similarly. Browser compatibility hacks became unnecessary.
• Frameworks emerged: React, Vue, and others replaced jQuery for complex UIs.
• Performance mattered: jQuery had overhead. Lean, native JavaScript was faster.

jQuery is still used in legacy projects and in WordPress (for admin features), but it's no longer recommended for new projects. Modern JavaScript is powerful enough without jQuery, and modern frameworks handle DOM manipulation more efficiently.

jQuery was a bridge between IE 6 and modern JavaScript. That bridge is no longer needed.

Dying Web Technologies

Plugins That Tried to Replace the Web

Beyond Flash, there were other attempts to replace or supplement web technologies with proprietary plugins.

Java Applets were small Java programs that ran in the browser. They were slow, required the Java plugin, and had a clunky user experience. They were used for educational purposes but never achieved mainstream adoption.

Microsoft Silverlight was Microsoft's answer to Flash. It was faster and more elegant, but it required a plugin and only worked on Windows (and Mac with a third-party effort). When Apple rejected Silverlight on iPhone, it was effectively dead.

The pattern is clear: proprietary plugins lose to open web standards. Every time, without exception.

The reason is logical: plugins create friction (users have to install them), lock-in (developers are dependent on the plugin vendor), and security issues. Open standards, by contrast, are freely available, don't require installation, and benefit from competitive development.

Third-Party Cookies: Dying for Privacy Reasons

Third-party cookies are cookies set by domains other than the one you're visiting. Advertising networks use them to track you across websites. Publishers use them to measure audience reach. They're the primary technology behind behavioral advertising.

For decades, third-party cookies were foundational to ad-tech and web analytics. But privacy concerns grew. In the EU, GDPR (2018) heavily regulated third-party cookies. Apple's Safari and Firefox blocked them by default. Google announced plans to deprecate third-party cookies in Chrome.

By 2023, major browsers had eliminated third-party cookie support or were planning to. Google has delayed its transition but hasn't abandoned the goal. The ad-tech industry is scrambling to develop alternatives (FLoC, Topics API), but third-party cookies as the dominant tracking mechanism are dying.

For website builders, this means analytics and advertising are shifting toward first-party data collection. Privacy-respecting analytics (Plausible, Fathom) are becoming more popular. Publishers are building direct relationships with audiences rather than relying on third-party tracking.

Classic Shared Hosting: Squeezed Out by Better Options

In the early 2000s, shared hosting (where your site shares a server with hundreds of others) was the default for small websites. You'd get 500MB of space for $5/month. It was cheap and easy.

But shared hosting had fundamental problems:

• Slow: Shared servers with hundreds of sites are overloaded. Performance suffers.
• Unreliable: If another site on the server gets hacked or crashes, your site can be affected.
• Limited control: You have minimal ability to configure the server or install custom software.
• FTP management: Files were managed via FTP, which is insecure and clunky.
• Inflexible: As your site grows, you outgrow shared hosting quickly.

Modern alternatives are better: VPS (Virtual Private Server) hosting, cloud platforms (AWS, Google Cloud, Azure), and managed hosting (Heroku, Vercel, Netlify) all offer superior alternatives. They're more expensive than cheap shared hosting, but they're more reliable and performant.

Shared hosting still exists and is still cheap, but it's not recommended for anything serious. The market has moved to better-designed alternatives.

The Pattern: Why Technologies Die

Looking at dying web technologies, several patterns emerge:

• Proprietary technologies lose: Flash, Java applets, Silverlight—all proprietary. HTML, CSS, JavaScript—all open. Open wins.
• Fundamental limitations cause death: Flash couldn't support mobile. IE couldn't support standards. These weren't fixable.
• Better alternatives matter: jQuery didn't die because it was bad—it died because modern JavaScript is better.
• Ecosystem matters: Shared hosting lost to cloud platforms that have better ecosystems and tooling.
• Security and privacy matter: Third-party cookies are dying because of privacy concerns, not technical limitations.

When choosing technologies for a new project, choose open standards, avoid proprietary lock-in, and pick technologies with active ecosystems. History shows that's where the future lies.

What's Next to Decline?

It's hard to predict which technologies will decline. But based on patterns, watch out for technologies that are: proprietary, have limited ecosystems, solve problems that new technologies solve better, or have fundamental architectural limitations. The web moves fast, and today's essential technology can be tomorrow's relic.
