BlueRay came out in 2006, there are Teens that have probably never seen a CD or DVD.
Blockbuster died around 2010, apple stopped shipping optical drives in the last of their computers around 2013, Streaming became the norm, there might be teens that haven’t used “Discs” for video and have streamed everything.
Got one living with me who falls into this category. She about lost her mind when I showed her a laser disc; thought it was some kind of special record. Yes, that’s the world we live in, now: kids collect records and cassettes, but have never seen a blu-ray.

Even more so when you realize they aren’t even digital, they use analog NTSC, PAL signal modulation / encoding.

Well, there was something like that. CED: https://en.wikipedia.org/wiki/Capacitance_Electronic_Disc
To be fair, adoption of bluray took a bit of time. The cheapest blu ray player was the PS3, and that was like 600$
I have never used a blu-ray. By the time they came around I was either pirating or streaming everything.
