 Well, we started with vinyl, and that's kind of coming back. But in between, we had the 8-track tape in the late 60s into the early 80s. Then we had the first karaoke machines, by the way, were all 8-track. The compact cassette tapes, they were smaller. They could last longer, 40, 30, 5 minutes. But 45 minutes, I should say, aside. And so they had that going for them. Yeah, and then they were replaced by CDs mostly in the 90s.
