More I Don't Understand...

The blimp has become a fixture at sporting events in the United States. (I don't know whether this phenomenon exists outside of the states, but that's not the part I don't understand.) Whether it's the Goodyear blimp, DirecTV's Airship, or one of MetLife's Snoopy fleet, they provide incredible aerial coverage of any number of sporting events. My personal favorites are the overhead views of golf shots. But they also provide coverage of football, racing, and occasionally baseball. But the NCAA Basketball tournament? This is truly March Madness. Yes, the blimps provide nice aerial shots of the host cities, but nothing of the games inside. Do we really need these overhead shots of the arenas?
