It being the Olympics right now, I was thinking back about watching Olympics hockey broadcasts back when I was a kid. Satellite transmissions from who-knows-where in Europe, 'snowy' picture, 'ghost' images following the skaters around the ice. Heck, most of the time, you couldn't even see the puck; you had to infer where it was from the movements of the skaters around the rink.
But, you know, that was over fifty years ago, so....
Anyway, I found myself thinking about that during the Wisconsin - Ohio State game...
