1440Gutenberg invents printing press
Books for the masses
Johannes Gutenberg's movable-type printing press revolutionized communication and made books affordable for the first time.
History Explainer · Technology
Technological change has a habit of compressing. Nearly four centuries separate Gutenberg's printing press from the telegraph, but only 66 years separate the Wright brothers' 12-second flight from the Moon landing — and barely 35 separate the first clunky mobile phone call from the iPhone. Reading the timeline in order makes that acceleration visible in a way no single fact can.
This page collects every technology event in the Chrono Trivia database in chronological order: printing, steam, electricity, radio, the transistor, the personal computer, the web, the smartphone, and the AI systems of the 2020s. Each entry includes the year, a short description, and the longer story behind the breakthrough.
This timeline covers 193 events from 1440 to 2024, grouped by era. Every event below can appear in the daily Technology puzzle.
