The Jetsons TV series which started in 1962 did a pretty good job of forecasting the future. Here's how their writers saw the future of football. Jetson's Night Out was broadcast during their first season 1962-63:
George Jetson and his boss Cosmo Spacely attend a robot football game. George fools his wife into thinking he's working late and so he won't be able to attend a PTA meeting.
Domed Football Stadiums. The Astrodome, in Houston Texas, was the first domed sports stadium. It opened in 1965. Astro was the name of the Jetsons' family dog.
