It is unclear how Netflix would change, if it would change at all, should Disney actually make the purchase.
It is also probably a lot easier and practical (assuming you have the amount of money that Disney does) to purchase Netflix instead of starting their own streaming service and trying to gain their own subscriber base.
So really Disney would be trading in the revenue stream that Netflix gives them now for their entire revenue stream but more importantly, their platform.
It looks like Disney isn’t going to be content with ruling Hollywood and the box office for the foreseeable future.
