A five-part history of computing produced by WGBH and the BBC, tracing the machine from wartime code-breaking to the desktop era. Archival footage covers the Colossus and ENIAC projects, the Cold War funding that built early mainframes, and the shift from room-sized calculators to machines ordinary people could use. Interviews bring in the people who built the field, including Grace Hopper on early programming languages and researchers who worked alongside Vannevar Bush and J.C.R. Licklider on the idea of computers as tools for thought rather than just calculation. Later episodes follow the rise of personal computing, the birth of artificial intelligence research, and the arguments over what machines should and shouldn't be trusted to decide. The series moves chronologically but keeps returning to one question: how a device built to crunch artillery tables ended up rewiring how people work, communicate, and think. Narration stays factual, letting period footage of vacuum-tube computers and early networking demonstrations carry the sense of how fast the ground shifted.
