Now that many of the streaming services are realizing that they just can't spend tons of cash on content to boost subscriber numbers and profit matters I think it's only a matter of time before the number of services implodes. Personally, I can't wait.
Look at the CW. From what I understand, as a network, it was never profitable but it made money licensing their shows to Netflix. Then the decision was made to bring all of those shows in-house and stop licensing them and then the CW was really unprofitable and it started collapsing and it was sold off. They could have continued making money by licensing their content but chose not to. Sony has TONS of content but doesn't have a streaming service; I wonder why? The current deluge of streaming services is, hopefully, unsustainable.
