How'd They Do That?

Ever wonder how they draw that yellow line across the football field marking the first down? This is why productions are such costly processes:



Think about it. That’s a lot of machines and people needed to slap that yellow line down. And on top of that, a bunch of engineers had to sit around for what I’m sure was quite some time to figure out how to merge all the available technology together to paint a line on the television screen telling you how far your team has to go to get the first down. That’s nuts.
