Beer v. Sun - Are Brown Bottles Better?

In the eternal battle of truth versus advertising, David asked The Straight Dope's Cecil,

The current ad campaign for Samuel Adams beer makes the somewhat dubious claim that the company’s beer, stored in brown bottles, is better preserved than beer in — eew! — clear or green bottles. So, time to break out your beakers (and beer bottles) and tell me if there is any validity to this claim, or if it's just the usual marketing babble.

So Cecil set some homebrew out in the sun in different colored bottles.  Click here to see the results.  (Spoiler Alert: Brown bottles win.)

That tells me even the clear commercial bottles include some measure of coating against light.

Beer poured into a glass will skunk in as little as 15 minutes in full sunlight.

I heard an interview some years ago that said hop extracts are used in Corona and Newcastle, and that's why they can be sold in clear bottles. hop extract is more stable than leaf hops. I think it was a Jamil Show on Brown Ale in 2005 or 2006.
