I don't get what you're implying. What did you want them to do? Install a stripper pole and start serving drinks?
BlockBuster, itself, has adapted to the market, introducing BlockBuster Online. Is it as good as Netflix? I don't think so, but that's like saying that Pepsi isn't as good as Coke -- that doesn't mean that Pepsi didn't adapt to the market or their customer base. BlockBuster is best characterized as the second most successful online DVD rental service, not the least successful.
And with regard to the brick and mortar, my position is that the
best way to adapt to the market is to
close the stores down -- that's exactly what BlockBuster is doing. Seems to me that they're handling that
correctly. There is nothing that they can do to control the fact that landlords want rent, and municipalities want taxes, and that'll amount to more than any form of DVD rental service provided in storefronts is really worth, these days.
