Before the web could carry rich media reliably, the most engaging interactive experiences shipped on a disc. The CD-ROM presentation — a self-contained multimedia catalogue, portfolio, or training programme — was a genuine craft, and much of what it taught still shapes good interactive content today. This article traces that lineage and brings it up to date.
The CD-ROM era and what it got right
For a stretch of the late 1990s and early 2000s, a CD-ROM was how a company handed you a polished interactive experience: menus, images, audio, video, and simple animation, all running instantly from local storage without waiting on a dial-up connection. The medium forced discipline. Storage was finite, so every asset had to earn its place; there was no "just add another page." Designers learned to structure information tightly, guide attention deliberately, and make navigation obvious — lessons that transfer directly to any interface.
Why it moved to the browser
The disc's strength was also its weakness: once pressed, it could never be updated. As broadband spread and browsers grew capable of smooth media and rich interaction, the advantages flipped. A web-based presentation is instantly updatable, reaches anyone with a link, works across devices, and can measure how it is actually used. The self-contained disc gave way to the always-current page, and the craft migrated with it.
Interactive content today
Everything the CD-ROM did, the modern browser does better and reaches further. Rich media, animation, and interactivity are now native to the web platform, no plug-ins required. The Canvas API, SVG, CSS animation, and standard audio and video elements let a page do what once needed specialised authoring software. An interactive product catalogue, a guided walkthrough, a data-rich explainer — all now live at a URL.
The principles that survived
The tools changed completely; the craft barely did. Good interactive content still respects the same rules the disc era enforced: a clear structure the user can hold in their head, obvious navigation, media that serves the message rather than decorating it, and restraint that keeps the experience fast. If anything, the web's freedom from a storage limit makes that restraint harder and more important.
Accessibility: the modern requirement
One thing the browser adds that the CD-ROM never had to reckon with seriously is universal access. Interactive content today must work for people using keyboards, screen readers, captions, and assistive technology — a baseline codified by the W3C Web Accessibility Initiative. Rich and interactive does not mean exclusive; the best modern presentations are engaging for everyone, by design.
Where to go next
The techniques behind interactive content are the same ones covered in Web Development, and the design discipline it demands is the subject of The Craft of Web Design.
Portfolios and catalogues, then and now
The classic use of the interactive disc was the showcase — a portfolio, a product catalogue, a company overview handed to a client as a polished object. Those needs never went away; they simply moved to the browser, where the same content can be updated the moment a price changes or a project ships. The lesson the disc era teaches the modern portfolio is curation: because the old medium could hold only so much, it forced its makers to choose their strongest work and present it with intent. A web portfolio has no such limit, which makes the discipline of choosing what to leave out the harder and more valuable skill.
