Hello, old friend… (Linus Tech Tips - Ripping your discs and the benefits of physical media)
Linus Tech Tips - How to rip blurays/4K discs to your own server and reencode then if you want to, the history of copy protection and the benefits of physical media. Quite interesting.
That's just recordable Blu-rays, for the 5 people that have a Blu-ray writer. Nobody uses them, USB drives are far more convenient and can be bigger anyway.
Pressed discs are alive and well. Sony has been outsourcing Blu-ray manufacturing for years anyway, so the recent announcement changed nothing. BD-Rs are probably on life support, though.
