I purchased some movies and TV shows on Amazon Prime about ten years ago. I had them downloaded for my private use, but there was a catch. They could only be watched using the Amazon player and had to be connected to the internet to validate them. This meant I only had use of them if I had that Amazon Prime account. When I canceled my original account with Amazon and created a new one, I no longer had access to the movies I purchased. I didn't have physical ownership of them anyway. It was a total ripoff. They have since changed their policies on entertainment content. In other words, I never owned them for my use at all. And once I cancelled my account, I had no access to them. And they weren't cheap.

I still purchase physical media. I know I'm old fashioned etc. But principally because I buy from as close to the artist as i can generally so they get the most income.

Digital ownership where you access something as a service is not 'ownership'. SaaS - Something as a Service (be it sex, software, etc.).

By 'owning' you have full total 100 percent rights to use the device, thing, or item in any way you like because you bought and paid for it. No ongoing subscription, no requirement to connect to the Internet for authentication, etc.

Otherwise it's not 'owning'.

If you bought a new car and were told you had to 'subscribe' after handing over the money to actually be able to use the car, would you think you 'own' it? We already 'subscribe' by having a drivers license and registration to access public roads, but the vehicle itself belongs to the owner (unless it's leased - then it's jointly owned).

Can that happen? Has it ? I’m not up on technology like I was back in the day.

DVD sales are declining, and some retailers are phasing them out, but DVDs are not being entirely discontinued. Some retailers, like Best Buy, are discontinuing DVD sales, but others, like Amazon, continue to sell them. Streaming services have become the dominant way to consume movies and TV shows.

Or there has been a storm and your Internet is out. Put a DVD in your player and watch a movie. We have a DVD player in our motorhome. When we travel we always bring about 30 movies with us. Internet is not always available.

Same with videogames, you cant own a hard copy anymore.... matter of fact you never own the actual game when you get it off steam

And this is why sales are down.
Memberships and subscription only deals only appeal to substantially lower numbers making the tv; music and movie market unsustainable.

Eventually, hopefully soon, the entire Internet will crash and burn. There are probably a million twelve-year-old boys working on it right now in their mother's basement.
