The 1990s

The destruction of the Berlin Wall in November 1989 disrupted the global balance. This fracture in history created fertile ground for digital technologies that were waiting to spread. The redrawn geopolitical landscape changed the stakes for computing and its dissemination.

When Soviet republics opened their doors to Western technologies, they unlocked unsuspected markets for computer firms. Eastern mathematicians, renowned for their excellence, shared their approaches with their Western colleagues. This intellectual cross-fertilization enriched computer science thinking on both sides.

The 1990s saw the global economy break free from traditional barriers. Large corporations had to adapt to this new reality: managing planetary operations required information systems capable of processing mountains of data and synchronizing activities across time zones.

Finance underwent a radical transformation. Transactions became dematerialized, algorithms invaded trading floors. Stock exchanges multiplied the pace and volume of exchanges, demanding ever faster machines and ever more robust networks.

The Internet left the closed circle of academics and military personnel to invade the daily lives of individuals. Internet service providers flourished, first with modest modem connections that whistled and crackled, then with increasingly generous bandwidths. This opening gave birth to new services and modes of communication.

Citizens created their digital spaces of expression. Forums, electronic messaging, and personal websites wove invisible links between individuals. Virtual communities formed, bringing together enthusiasts across distances. This new socialization transformed user interfaces, which now had to appeal to an audience unfamiliar with computing intricacies.

Computers became fixtures on every professional desk. Companies massively invested in hardware and training. Word processing buried the typewriter. Spreadsheets conquered management. Slideshows revolutionized meetings by replacing transparencies and their overhead projectors. This rapid computerization created a voracious appetite for software adapted to professional realities.

In schools and universities, computing found its place in curricula. Computer labs became familiar places for students. This evolution responded to the demands of a job market seeking technical skills.

Video gaming transformed into a major industry during this period. Consoles pushed technical boundaries, with increasingly striking graphics. This sector energized research on graphics processors and brought computing into households through the gateway of entertainment.

Digital works flourished with the advent of multimedia. CD-ROMs made it possible to combine text, images, sounds, and videos in an accessible format. Digital encyclopedias revived knowledge. Entertainment applications breathed new life into personal computing.

Electronic components continued to shrink, giving birth to the first consumer laptops and personal digital assistants. Mobility became a requirement, forcing the adaptation of interfaces and operating systems.

Mobile telephony experienced explosive growth. Digital networks deployed across cities and countryside. Text messages invented a new language, concise and immediate. The future fusion between telephone and computer was becoming apparent.

Administrations modernized their IT infrastructures, digitized their dusty archives, and developed the first online services for citizens. These large-scale projects stimulated the market for professional solutions.

With the multiplication of connections, security became a central concern. The first viruses targeting personal computing sowed panic, followed by the development of antivirus software and firewalls. The protection of personal data emerged as an issue for the dawning 21st century.

Free software found its way with GNU and Linux. This alternative philosophy to proprietary software disrupted established models by proposing a collaborative and open approach to software development.

The final years of the decade saw the flourishing of the first online stores and the swelling of the Internet bubble. Investors rushed toward anything related to digital technology, sometimes with more passionate than rational fervor. The bursting of this bubble awaited at the turn of the millennium.

This decade changed our relationship with computing. Computers settled into our daily lives, transformed our professions, modified our leisure activities. They were no longer these strange entities confined to air-conditioned laboratories. The household equipment rate soared, reaching 23% in France in 1999, compared to barely 8.5% in 1990.

The world discovered itself connected, without yet fully measuring the consequences of this transformation.

Computing in the 1990s cannot be reduced to a simple technical evolution; it constitutes an anthropological rupture whose magnitude we are only beginning to perceive.
