Key Milestones in Moore's Law History

1965, The Original Observation: Gordon Moore publishes his observation in Electronics Magazine, predicting annual doubling of transistor counts on chips.

1971, Intel Co-Founded: Moore co-founds Intel, which becomes the primary proving ground for his prediction over the following decades.

1975, Revised to 24 Months: Moore revises the doubling period from one year to approximately every 24 months, the version that became the canonical law.

1990s, Industry Adopts as Roadmap: Semiconductor industry formally aligns R&D investment cycles and manufacturing roadmaps around Moore's Law as a planning target.

2010s, Physical Limits Emerge: Engineers begin encountering the physical limitations of silicon at atomic scales, slowing the pace of traditional transistor density gains.

Recent, Law Holds, Then Slows: As noted by TechRadar, Moore's Law held up for many years before engineers finally reached the physical limitations of silicon in the last decade or so.
