When you watch football on TV, you've probably noticed the superimposed yellow line that marks the distance to the next set of downs. The line looks simple enough and as though it's something standard that probably doesn't cost much, but in reality, it costs between $25k and $30k per game.
In a nutshell, the whole thing requires 3D scanning of stadiums, analysis of camera angles and position, and it's own dedicated team to manage, which, over the course of a season, amounts to nearly $5.2m.
That's 3x the salary of an average kicker. For a yellow line.
