alt Hacker NewsI'm most certainly not a football fan, but I definitely know that a match consists of two 45 minute (and then some) halves. It's pretty much equivalent to a non motor enthusiast knowing that there are usually four wheels on a car.
I'd say this is very, very common knowledge in huge parts of the world. It's not something only enthusiasts and purists know.
Sure, but they aren't leaving the field. There are plenty of stoppages in game already which take as much time. In that sense it's nothing new. Do non-fans view it as changing to 4 "quarters"? I'm not sure most people would care. This is what I mean it's the kind of thing that football purists care about but it's a very small thing.
