On April 8, 1966 — At the Astrodome, the Astros and Dodgers play baseball’s first game on synthetic grass. Thanks to the Monsanto chemical company, who proposed using an experimental playing surface of nylon grass, the plan to play on an all-dirt field, necessitated by the need to paint the dome’s glass panes to reduce the glare which prevented natural grass from growing, was alleviated by the use of ‘AstroTurf.’
