History of Data Science
The foundations of data science were laid decades before the term became popular:
Key Milestones:
- 1960s: John Tukey introduces “data analysis” as a scientific discipline.
- 1974: Peter Naur first uses the term “data science” in his book Concise Survey of Computer Methods.
- 1996: The International Federation of Classification Societies (IFCS) officially recognizes data science as a field.
- 2000s: The rise of Big Data (Hadoop, Spark) and Machine Learning accelerates demand.
- 2010s-Present: AI-driven analytics, deep learning, and automated tools revolutionize the industry.
Today, data science is a $100+ billion industry, with applications in healthcare, finance, retail, and more.
