In the beginning, experts swore television would never matter. Viewers would tire of “staring at a plywood box.” Baseball could never be captured on one screen, and no one would trade the color of their imagination for grainy black-and-white flicker. And yet, one messy, chaotic, barely-watchable baseball experiment in 1939 sparked a revolution. In this episode, I trace the improbable origin story of baseball on television, from the fuzzy “little white flies” of the first broadcast to the national shared experiences that made America rush to buy a set for themselves. This is the story of how a single game, and a single swing, helped sell a country on an idea that would transform the future.
