Colbert nails bovine growth hormone

While I enjoy The Colbert Report when I see it, it’s not something I typically go out of my way to watch. That said, when Ange sent me a link to this piece about bovine growth hormone, it occurred to me that instead of merely watching the show, I should study it as part of an official curriculum in activism and marketing. How is it that the AR side, with a few exceptions, is still basically showing the same slideshow of slaughterhouse footage while a show like The Colbert Report can make something like this just to get a few laughs for 3 minutes and then it’s never to be seen again (interweb notwithstanding)?
