Not so sure that the bankrupted blockbuster is a great example of how a business should be run.
Blockbuster failed for a few reasons chiefly that they didn't adapt to the internet fast enough. However their rental model did not bring in the revenues.
Whereas the competition, Netflix, did offer similar services (rented movies) for a flat subscription. Yes, Netflix also offered it via mail, however the Netflix model has (nearly) always been a flat subscription for its movies.
Arguably, using evidence we've seen in real life, the subscription model is preferred by consumers and businesses alike. (Note: I don't like them and have strived to cancel most of the subscriptions services I use)
Fastmail also offers this.
Curious to know how many others do as well.
