They are sold, but no one is using it. Like, my PC hasn't had optical drive for like a decade now if not more, my oldest laptop still has one, 2 newer ones didn't come with one at all. My car has CD player still, but I 3D printed a phone holder and jammed it in there and my phone is playing music via BT adapter and into AUX. And even before this, I bought the car specifically with USB port that plays MP3's and I've not listened to it that way for years now. But it's there. Can't imagine listening to CD's in a car these days...
