Alright then, let me rephrase what I was trying to say. People caught on to breaking bad late, got caught up through Netflix or whatnot, and blew up the final 8 episodes and because of the hiatus in season 5, it helped fuel that hype for the final 8.
Whereas TWD really caught mainstream from the beginning, so instead of a huge market increase all at once (like BB did), it's been steady -- starting well in season 1 and continuing to grow.
I didn't have any numbers to aid my point, so I just threw out season 4. Obviously, that wasn't a good place to start, because you just told me the ratings jump didn't happen until season 5.
