> It is way cheaper long term.

I would think this is only true if you watch a small number of shows and rewatch them often

They're $20-50 for complete series on dvd on Amazon right now. That's 14-35 new shows to get every year for the same price. I believe it's cheaper. This is why so many companies push subscriptions. If DVDs made them more money than they'd be pushing you to buy them.
