Contrary to popular belief, disc based media isn't going anywhere. Not in this service provider bandwidth bottleneck and data capped country. Microsoft has been trying (and failing) to "take over your living room" by installing voice activated, all-in-one entertainment systems in every living room for a dozen years. Then there's Net Neutrality getting repealed. Fun times.
BDs are king. I basically don't go to the movies as often as I did when I was younger. AMC theaters average about $14. It's a ripoff. Three months later you can get the disc instead. I buy BDs for under $10 and 4K movies I want to see at $15 or less. The home theater and television experience is better than ever before. Just look at what you could buy for only $1500 this year. Seriously, go in the store and look at it. Some people care about HD and picture quality the same way others care about their 1080 graphics cards. It's just a different hobby.
On the other hand, 2017 is the first year in many years where it is worth going to the theater again. A few 'Emagine' theaters in our area have ripped out all the airplane seats and now there are half as many full-sized, luxury, leather, electric recliners than there were seats before. They are super comfortable and there is about three feet of room in front of you to stretch out. Everything is clean and remodeled and now there is a full liquor bar. Icees and sodas are self-serve with free refills. Tickets are $6-10 depending on the time of day. It's actually worth going to the movies again. It's astonishing.
You still can't beat getting your favorite television seasons on HD discs for $20/season though. People buy $400 big screen TVs and rent DVDs from Redbox the same way McDonalds serves millions of customers a day. The people that criticize home media purchasing usually have no taste themselves. They can switch over to streaming and do what they do, while forecasters denote the decline in physical media revenue year over year. But the enthusiast market ain't going anywhere. We're the ones who spend on this stuff.
