The History of Artificial Intelligence: From Theory to the Tool Reshaping Business

RYYZZE · Louise Reid·19 May 2026·8 min read

AI feels like it arrived overnight. It did not.

The story of artificial intelligence spans more than seventy years of research, failed experiments, landmark breakthroughs and periods where the entire field was written off. Understanding that history is not just interesting. It is practically useful, because it tells you what AI is really capable of, why it works the way it does, and what to expect from it next.

The Beginning: 1950s

The formal birth of AI as a field is typically traced to 1950, when British mathematician Alan Turing published his landmark paper "Computing Machinery and Intelligence." In it, he posed a question that still resonates today: can machines think?

Turing proposed what became known as the Turing Test — a framework for evaluating whether a machine could exhibit intelligent behaviour indistinguishable from a human. It was theoretical, but it set the conceptual foundation for everything that followed.

In 1956, John McCarthy coined the term "artificial intelligence" at the Dartmouth Conference, bringing together the researchers who would define the field for the next two decades. The early optimism was extraordinary. McCarthy himself predicted that machines with human-level intelligence were perhaps twenty years away.

The First AI Winter: 1970s

Progress was slower and harder than expected. Early AI systems could solve problems in controlled environments but struggled to generalise. Funding dried up. The field entered what became known as the first AI winter — a prolonged period of reduced investment and diminished expectations.

The core problem was that rule-based systems, which underpinned most early AI, required humans to define every possible scenario and response. The real world was too complex and unpredictable for that approach to scale.

Expert Systems and the Second Winter: 1980s

The 1980s brought renewed optimism through expert systems — software designed to replicate the decision-making of human specialists in narrow domains like medical diagnosis or financial analysis. Businesses invested heavily.

The results were mixed. Expert systems worked well within tight parameters but were expensive to maintain, difficult to update and brittle when faced with scenarios outside their programmed knowledge. By the late 1980s, the market had collapsed and the second AI winter had arrived.

The Quiet Revolution: 1990s

Whilst public interest had waned, important research continued. A shift was underway from rule-based approaches to machine learning — systems that could learn from data rather than following explicit instructions written by humans.

In 1997, IBM's Deep Blue defeated world chess champion Garry Kasparov. It was a landmark moment, widely covered in the press, though Deep Blue was a narrow system designed specifically for chess rather than a general intelligence. The significance was symbolic as much as practical.

The Modern Era: 2000s to 2020s

The 2000s brought an explosion of data, driven by the internet, and the computing power to process it. This combination proved transformative for machine learning.

In 2012, a deep learning system called AlexNet dramatically outperformed competitors in an image recognition competition, demonstrating that neural networks trained on large datasets could achieve results far beyond what rule-based systems could manage. The modern AI era had begun in earnest.

By the mid-2010s, AI was embedded in everyday products — recommendation engines on Netflix and Spotify, voice assistants on smartphones, fraud detection in banking. Most people were using AI constantly without calling it that.

In 2022, the public launch of ChatGPT brought generative AI to a mass audience for the first time. Within two months it had reached one hundred million users, faster than any consumer application in history. The conversation changed permanently.

Where We Are Now

Today's AI tools can write, code, design, analyse, translate, summarise and generate content across formats with speed and quality that would have seemed implausible a decade ago. The technology has moved from research labs and large enterprises into the hands of small businesses and individual operators.

The businesses that understand this shift — not just as a technology trend but as a structural change in how markets operate — are the ones positioning themselves to lead in the years ahead.

What This Means for Your Business

The history of AI teaches one consistent lesson: the businesses that adapted early at each inflection point gained advantages that were difficult for later movers to close.

We are at another inflection point now. Not the last one, but a significant one.

The question is not whether AI will change how your business operates. It is whether you will shape that change deliberately, with strategy behind it, or react to it after competitors have already moved.

At RYYZZE, that is exactly the work I do with leadership teams — helping businesses understand where AI genuinely adds commercial value and building the strategy to capture it. If you want to think this through for your business, get in touch.
