Please forgive me definitely Amazon Prime(which we have also annually),it's just when you get 2 for 1(Movies& Free Shipping) it really does'nt seem to qualify as a bill to me.Now that you mention it, Amazon Prime (which includes other stuff) has an annual price. I also know Tennis Channel, Brit Box, Acorn TV, Curiosity Stream and some of the classic and indie movie services do too. I'm sure there are plenty of others outside of the MVPD services, Netflix, Hulu, and CBS All Access.
Not that big a deal to just sign up the last month alone. That's what I did when GOT was on.I do not think we are that far off from the steaming services not release a full season at one time. I am not sure it will be a weekly release but I can see for a 12 episode season that they release 4 episodes at the start of a month for three months. If there are enough jumping in and out to binge watch this will happen IMO. Now you can wait until they are all released but many will not want to.
There's only thousands of free programs and movies. There's also thousands of programs that aren't free.I thought that I was suppose to get "free" content through my Amazon Prime membership.
