At least in the case of Blockbuster, I'd say the lag can be accounted for by the fact Netflix got into streaming in 2007. Prior to that Netflix started eating Blockbuster's lunch, but the service really took off once they managed to mainstream streaming. This was helped, in no small part, by the rapid rise in broadband penetration of that same time period.
