"Now"? Dude, that's the way it's always been, directors prove their big ideas in music videos, and once they're realised clients "get it" and dare to hire the director to do the same again.
Also known as "demo love" when things end up looking exactly the same. ;)

It's a Two hour DVD study aid, I doubt anyone will rip that and upload it.

That's an awesome looking ad despite youtube's pxellated jumpy look. ;) I wonder who directed, and how it was made.

Jack saying that the commercial inspired him implies that the ad was made befor ethe song. Unusual tactic.
