Advent of Computing

Sean Haas researches one piece of computing history per episode, often a machine or idea that broader histories skip, such as Olivetti's Programma 101 or RAYDAC, the computer Raytheon contracted to build in 1947. The research is careful and the tone conversational, with enough context for a newcomer to follow. New episodes arrive every week or two and the feed now holds more than 200, so begin with whichever subject catches your eye rather than at episode one.
