Optical disc technology was pioneered by American engineer David Paul Gregg, who patented his “Videodisk” system in 1962 and 1969. Although designed for analog video, his work introduced key principles of optical recording that later informed the development of compact discs.
In the 1960s, James T. Russell, working at Battelle Memorial Institute, developed an early system for optical digital recording and playback. By encoding audio as digital data and storing it on photosensitive materials, his work anticipated the principles behind the compact disc.
Introduced in 1971 by IBM, the floppy disk became a widely used magnetic storage medium for data transfer. Over time, its size evolved from 8-inch to 5.25-inch and finally to 3.5-inch formats. With a capacity of up to 1.44 MB, it was far more limited than CD-ROMs, yet remained essential for software distribution and data exchange throughout the 1980s and 1990s.
After several years of research into optical recording technologies, Philips officially launched a project to develop the Compact Disc in the mid-1970s. Building on its earlier success with the Compact Cassette, the company sought to create a high-quality digital audio format based on optical storage.
The LaserDisc (LD), developed by MCA DiscoVision in collaboration with Philips and drawing on earlier optical disc research by David Paul Gregg, was the first commercial optical disc format. It stored analog video and audio signals and required optical playback, but unlike later compact discs, it was not a digital medium.
In 1979–1980, Philips and Sony worked together to define the Compact Disc. Through a series of meetings in Eindhoven and Tokyo, they established a unified technical standard that would become the foundation of digital audio.
The unified standard for all audio discs, developed jointly by Philips and Sony, defines the specifications for compact discs, including dimensions, materials, and more. The disc's diameter was set at 120 mm to ensure it was compact compared to vinyl records and could hold Beethoven's entire 9th Symphony (74 minutes). Standardization meant that any CD could be played on any CD player. The Red Book became the first standard in the Color Book series of standards, which together define various CD formats.
Sony released the Sony CDP-101, the first commercially available CD player. This marked the arrival of the compact disc as a consumer audio format, soon followed by competing devices from Philips.
One of the first commercially released CDs was "The Visitors" by ABBA, signaling the arrival of the compact disc as a new medium for music distribution.
The Yellow Book, introduced in 1983, defined the standard for CD-ROMs, specifying how data could be stored on compact discs. Developed jointly by Sony and Philips, it established a read-only format for storing binary data. These specifications made CD-ROMs suitable for a wide range of applications, from software distribution to multimedia storage.
Shortly after the introduction of the Compact Disc, researchers began exploring recordable optical media. At the 73rd Convention of the Audio Engineering Society, Kees Schouhamer Immink and Joseph Braat presented early results that would contribute to the development of write-once (WORM) optical discs.
Sony and Philips announced the CD-ROM format, extending the compact disc into a medium for digital data. In 1985, the first CD-ROMs were showcased by Denon and Sony at COMDEX Japan.
The Voyager Company, founded by Bob Stein and collaborators, worked at the intersection of film, publishing, and emerging digital media. It first became known through The Criterion Collection, which presented classic films on LaserDisc alongside commentary, trailers, and image galleries. The company later turned to interactive formats, experimenting with HyperCard to combine text, video, and sound. Its “book-based” approach to video and audio emphasized structured, reflective engagement with media, distinguishing it from more entertainment-focused multimedia products.
Portable CD audio devices, including car players and personal units, were introduced to bring CD-quality sound beyond the home. These devices made it possible to listen to compact discs while traveling, extending digital music into everyday mobile contexts.
The Philips CM-100, announced in 1985, is generally credited as the first CD-ROM drive. Priced at $1,495, it was designed for the IBM PC/XT and required a system with 256K of RAM and an available ISA slot.
Around 1985, CD-ROMs began to appear in libraries, initially used for cataloging and technical services. Reference works such as Ulrich’s Periodicals Directory, Grolier’s Knowledge Disk, and Compton’s Encyclopedia were among the first to be distributed on disc. Abstracting and indexing services soon followed.
The New Grolier Encyclopedia brought the encyclopedia to CD-ROM, adapting the content of the Academic American Encyclopedia into a digital format with around 32,000 entries. The early editions were text-only, without images, maps, or multimedia, reflecting the initial use of CD-ROM as a storage medium rather than an interactive format.
Sony’s Discman line introduced a series of portable devices designed primarily for audio CDs, bringing compact disc technology into everyday mobile use. These devices emphasized personal, portable listening, extending the model established by the Walkman. Initially celebrated for enabling private music consumption on the go (the so-called “Walkman effect”), the Discman line was complemented by related devices such as the Data Discman, which allowed users to access text-based content and electronic publications. Together, these developments broadened the use of CD-based media beyond music to include portable data access and information retrieval.
Industry representatives met at the High Sierra Hotel in Lake Tahoe, California, to develop a common file system for CD-ROMs. Published in 1986, the resulting High Sierra Format introduced a hierarchical structure for organizing data on disc, laying the foundation for later standards such as ECMA-119 and ISO 9660.
SilverPlatter Information developed CD-ROM versions of reference databases, replacing earlier distribution on magnetic tape. Beginning in 1986, its releases included databases such as ERIC, PsycLIT, and A-V Online. The company also introduced SPIRS, a proprietary interface that provided a consistent way to search across its databases, widely used in libraries. By 1997, its catalogue had grown to more than 200 titles.
Meridian Data developed systems for producing and distributing CD-ROMs at a time when the format was still taking shape. Its CD publishing technologies made it possible to store and replicate large volumes of data on optical discs for use in business, education, and government contexts. The company’s products, including networked CD-ROM solutions, were adopted by corporations, universities, and public institutions, supporting the early circulation of digital information on disc.
Introduced in 1986, LV-ROM (LaserVision Read-Only Memory) combined analog video and audio with digital data on a single disc. Developed within the LaserVision system by Philips, it offered an early model of interactive multimedia by integrating software and video. As a hybrid format, it bridged analog video technologies and emerging digital media.
The BBC Domesday Project, created to mark the 900th anniversary of the Domesday Book, assembled contributions from thousands of schoolchildren across the UK, documenting everyday life through text, images, maps, and data. Released on LV-ROM discs, the project soon became difficult to access as the technology fell out of use. Today, it stands as a key example of digital obsolescence and the fragility of multimedia archives.
The first CD-ROM conference, organized with support from Microsoft, gathered hardware manufacturers, software developers, and publishers around the emerging CD-ROM format. Part trade show, part meeting ground, it became a space where prototypes were demonstrated, partnerships formed, and expectations about multimedia computing began to take shape.
CD-ROM Review was one of the first publications dedicated to CD-ROM technology, aimed at helping users navigate a rapidly expanding field of software and multimedia titles. It reviewed new releases, introduced applications, and contributed to the emergence of a broader culture of CD-ROM publications, many of which were later distributed on CD-ROMs themselves.
Building on CD and CD-ROM technologies, the CD-i format enabled the integration of audio, text, and video, opening the way for interactive media. Developed by Philips and defined in the Green Book, it specified both the disc format and the required hardware. Until the mid-1990s, the technology remained largely under Philips’ control.
The Meridian Data CD Publisher, introduced by Meridian Data, was one of the first systems capable of recording compact discs. Large and expensive — comparable in size to a washing machine and costing around $150,000 — it operated at 1× speed, requiring real-time recording. Despite these limitations, it was widely adopted in the early CD-ROM industry and used to produce large numbers of discs.
Digital Video Interactive (DVI), developed by Intel, was one of the first systems to enable full-motion video playback from CD-ROMs using dedicated hardware for compression and decompression. Announced at the second Microsoft CD-ROM Conference, it allowed up to around an hour of video on a single disc and was designed for use with IBM-compatible PCs. As a hardware-based multimedia solution, DVI posed a significant challenge to CD-i, influencing its development and positioning in the market.
Released by Apple, HyperCard introduced a “stack of cards” metaphor for organizing information and enabled users to create interactive, nonlinear experiences by linking text, images, and sound. As an early hypermedia system, it became a foundational tool for experimenting with multimedia and interactive content.
Microsoft Bookshelf compiled several reference works into one digital library. It included a dictionary, thesaurus, quotations, a world atlas, as well as a hypertext engine, making it one of the first personal digital libraries.
The CD-Video (CD-V) format, introduced in the late 1980s, combined LaserDisc and compact disc technologies. It could store up to 20 minutes of audio and 5 minutes of video, making it primarily suitable for music videos. CD-Vs could be played on both CD-V and LaserDisc players. However, the format had a short market lifespan and was considered obsolete by the mid-1990s.
CD-ROM versions of bibliographies, such as Books in Print, were among the earliest formats to take advantage of the medium’s storage capacity and search functionality. These directories, listing available publications, demonstrated how large inventories could be organized and navigated digitally. At the same time, similar cataloging practices emerged for CD-ROMs themselves: first as printed directories, and soon as searchable databases distributed on CD-ROM, turning the medium into a tool for indexing its own contents.
By 1987, the CD-ROM market had yet to fully emerge. With only around 75 publishers and 100 titles worldwide, the field remained small and loosely organized. Standards were still in flux, and CD-ROM drives had only just begun to reach users beyond specialized environments. Most applications were institutional, centered on databases and archival collections rather than consumer media.
Developed by Philips, Sony, and Microsoft, the CD-ROM XA (Extended Architecture) format enabled synchronized playback of audio and data, supporting more advanced multimedia applications. Compatible with CD-i systems, it helped bridge the gap between CD-ROM and CD-i.
The adoption of ISO 9660 standardized the CD-ROM file system, ensuring compatibility across different computer platforms. Based on the earlier High Sierra Format, it enabled CD-ROMs to be used reliably across systems worldwide.
The CD-ROM² system, introduced in 1988 by NEC, was one of the first CD-ROM add-ons for a video game console. Known in the West as the TurboGrafx-CD, it connected to the console via an external interface unit. The system expanded storage capacity for games, enabling enhanced audio and more complex content. While it achieved success in Japan, it struggled in the United States due to high costs, limited software availability, and marketing challenges.
InfoTrac transitioned to CD-ROM, providing libraries with faster access to large collections of periodical indexes. Distributed primarily on disc for several years, it allowed users to search extensive archives locally, without relying on remote systems.
Apple CD-ROM Explorer, developed by Apple, was designed to demonstrate the capabilities of CD-ROM technology. Combining text, images, audio, and video, it offered an interactive environment for exploring digital content. Distributed to schools and institutions, it positioned CD-ROM as a medium for both education and entertainment.
“Fighting Street,” a CD-ROM adaptation of Street Fighter, was released in 1988 for the PC Engine CD-ROM². As one of the earliest games distributed on CD-ROM, it demonstrated the potential of the format for home consoles. The game featured audio and voice samples taken directly from the arcade version, even if overall performance and quality remained limited.
Compton's Encyclopedia introduced by Encyclopaedia Britannica Inc. was the first "multimedia" compendium featuring sound, music, and animated images. It included the complete text of New Compton's Encyclopedia, along with a World Atlas, U.S. History Timeline, Topic Tree and Picture Explorer, Idea Search and Title Finder. The CD-ROM was priced at $895.
The “Companion to Beethoven’s Symphony No. 9,” produced by The Voyager Company, combined a printed score, a high-quality recording by the Vienna Philharmonic, and commentary by Robert Winter. Built using HyperCard, it allowed users to navigate the symphony non-linearly, moving between musical passages, individual instrument parts, and contextual analysis. The success of this project paved the way for similar ventures, including a companion to Stravinsky's "The Rite of Spring".
Originally released in 1988 on floppy disks, "The Manhole" was re-released in 1989 on CD-ROM for the Macintosh. Created by brothers Rand and Robyn Miller and published by Activision, the game was hailed as the first fully interactive storybook for personal computers, aimed at children. It featured non-linear exploration of a fantasy world filled with secrets, puzzles, and Easter eggs. The original black-and-white version was distributed on five floppy disks, but as Activision enhanced the game with color, music, and video, CD-ROM became necessary, replacing what would have been over 450 floppy disks.
The first CD-ROM edition of the "Whole Earth Catalog" brought Stewart Brand's influential countercultural guide into the digital realm, utilizing hypertext and HyperCard software. While preserving the original catalog's ethos of open-access knowledge, this edition allowed users to navigate the content interactively.
In the early years of CD-ROM, “virtual shopping malls” emerged in the form of electronic product catalogs distributed on disc. Using slideshows, video clips, and audio, these catalogs recreated elements of the shopping experience in a digital environment. Users could browse products interactively and place orders by phone or mail. From retailers like Otto GmbH to car manufacturers such as Mercedes-Benz and Porsche, CD-ROM became a new interface for commerce.
In the early 1990s, LucasArts re-released its point-and-click adventure games on CD-ROM, enhancing earlier titles with voice acting, improved music, and higher-quality audiovisual elements. These versions demonstrated how the format could expand existing games by adding performance and cinematic qualities. The transition culminated in 1995 with "Full Throttle", one of the studio’s first titles designed specifically for CD-ROM.
“Treasures of the Smithsonian”, produced by Philips Media in collaboration with the Smithsonian Institution, presented selections from multiple museums in an interactive CD-ROM format. Users could browse objects by museum, category, date, or theme, with features such as zoomable images and audio commentary. It exemplifies an early collaboration between the tech industry and a major museum, as well as an early example of an interactive art database.
CD-ROM technology became a medium for distributing large-scale scientific data. A notable example is Magellan mission, launched by NASA in 1989 to map the surface of Venus. The mission’s image data was released on more than 100 CD-ROMs, containing high-resolution mosaicked images. These releases transformed scientific results into navigable datasets, positioning CD-ROM as a medium for both research and public access to large-scale data.
CD-ROMs helped establish “edutainment” as a distinct form. “Magical Dinosaur Tour,” developed for the PC Engine CD by Fun Project, combined informational content with animation and interaction. The disc functioned as an interactive database, allowing users to explore information about dinosaurs by searching and sorting entries. Animated sequences brought prehistoric scenes to life, demonstrating how dinosaurs moved, hunted, and behaved.
Philips and Sony introduced CD-R, a write-once format based on earlier WORM technologies. Unlike read-only CD-ROMs, it allowed users to record their own data, contributing to the rise of disc authoring and CD burning in the 1990s. This shift also affected the material structure of discs, replacing the aluminum layers of CD-ROMs with dye-based recording layers and reflective metals such as gold or silver.
The Multimedia PC (MPC) standard defined the hardware configuration required to run multimedia software on personal computers. Formalized by the Multimedia PC Marketing Council, it specified a Windows-based system with features such as 256-color graphics, 8-bit sound, and a CD-ROM drive, which became a key component of the setup.
