I found an article that documents the development change at News Network CNN from the waterfall method to Scrum.
The article documents the reasons on changing from Waterfall to Scrum, the challenges, the benefits and the outcomes.
Its surprising to me that CNN would use Scrum as I never really thought that they would have much development needs, but I suppose in the world of news where nothing stays still, Scrum would be suited as the possibility of having working software in a short space of time far outweigh the Waterfall method of having working software after a long wait.
