Well, in the case of music by the time they lowered albums at about 10$ the market was shifting.
I guess the same is going on with movies. I think the market would expand if prices were lowered, but it would take time. Some will always complain about prices... With Spotify music prices are vastly lower... Has the market expanded? Are they making the same less or more money as a whole? Even making the same miney with an expanded market its still a win as a tiny increase in prices would yeild a lot more money each time and more people are hooked and its easier to sustain the market as people talk with each other things like that.
Btw, as far as movie tickets go... Yeah those are too high too, its rare i go anymore... I used to have the whole slate cleared before... Then prices climbed, and climbed ...
No, before they sold MP3s, everyone said, OH we have to buy crappy albums. Then songs were a buck a song...HOORAY...oh wait now that sucks why is a dollar. No matter what happened, it was never enough. And no, they aren't making the same money.
As for movies, the point is that if you're asking for a brand new movie to be released at for less than the average movie ticket, you're asking too much. Wait a few years and buy older movies.
As for theaters themselves, just join AMC's Alist 20 bucks a month (give or take) and see any 3 movies/week
The fact is that movies are insanely expensive to make and aside from 4k, they're all cheaper than they were 20 years ago (in some cases cheaper even if you don't adjust for inflation). 4K catalog is cheaper than what they sold for 20 years ago on DVD (unadjusted for inflation).
But honestly, if you don't want to do that, just rent movies from redbox. If you sign up for their mail, you get codes that cut the rental price in half...sometimes I pay as little as 50 cents for a blu ray rental.
