Those probably drive new users and retain current ones.
It would be nice if media companies could stop trying to own the World and instead be content offering a good service for good compensation. When they get to that point they seem to go "well if we can force people to consume something else that they don't like as much then we can get even more customers". Bleurgh.
NBC already owns the production rights to the Office. Under agreements with the various Hollywood talent guilds, they are required to pay market value for distribution rights such as exclusive online streaming, because that money gets paid to profit participants like producers, actors, writers, etc.
However, NBC is considering rebooting or spinning off the Office with some of the original cast.
I couldn't give two hoots about most of their original stuff which has been laughably mediocre and designed by committee at best, and I have no problem watching it in 5 years time off it's any good.
I just want a media delivery service where I look for something and then it plays, and so far that doesn't exist...
Which means what they should be doing is reserving the latest season to themselves but making it so that everything else is available everywhere (assuming reciprocity). Then when season one drops on Netflix and Netflix subscribers like it, well, season two is out but only on Disney for the next year. And the customer might actually be willing to drop Netflix for Disney this year if they both have the same back catalog, when it wouldn't be worth it if you have to subscribe to both at once for that.
The result would be that a customer could get all content by subscribing to only one service and no piracy, but only if they're willing to be a year out of date for most of it, which still allows them to get multiple subscriptions from the subset of people with more disposable income. And it's not as if they don't make any money from licensing the old seasons to the other providers -- or make any money when the other providers license their old seasons to them and allow them to get more subscribers.
Their problem is they're overvaluing exclusivity for old content.
