A few days ago I was out with my girlfriend to have a beer and watch the soccer game between Romania and Italy, which ended with a 1-1 draw. There were two places side by side where you could drink beer and watch the game. One had a huge wide-screen TV and was full when we got there, and the other had a small black&white TV that's probably older than me, with a small antenna. Of course we settled for the small TV and watched the game with the few people that were around. Every time something interesting happened, we would lay down the beer glasses and turn our heads towards the TV, occasionally cheering and applauding. About 2 to 3 seconds later, the crowd in the other bar would do the same. Of course, being a digital TV it probably had some amount of processing lag. I don't know how much, so I'll cautiously add the delay from the cable provider who also does some processing and might suffer from additional satellite delay, as opposed to the analog TV which was about... 4 miles from the TV station. So there goes the live. Having sorted out the intriguing relative delay between the small crowd and the large one, I am only left to wonder what the absolute delay was between Zürich and that old real-time analog black&white TV.
