Studios absolutely depend on new movies and television shows to survive.
In this vertically integrated world of streaming services, this is because new content retains current subscriptions and attracts new ones.
These studios also have huge backlogs of content that they can depend on to generate some small amount of revenue. They can make endless remakes. They can reissue the same tired and staid movies and television shows again and again.
Eventually, these things run out, and the studios will have to start paying interest on their loans.
Netflix, for example, is probably in a hole too deep to climb out of.
@ajroach42 So, time to cancel some subscriptions.
