Only you can speak to your own memories, but the cassette tape was already good and dead in the market by 2001.

(For context, this was the rural US southeast, and our family did have disk players, we just kept using tapes for a while. I remember the library had a lot more children videos and audio books on tapes than disks.)
Our family was gifted a CD player in 94 or 95, and all my music that I purchased with my allowance from that point was on CD, even though the unit had 2 tape decks. Mom only bought CDs from that point as well. Then when I got my first car in 01, I installed a radio that was CD only, no tape deck.
