Cardiff City will be the 55th club to play at the top level since I started watching the game. Of that lot, 20 now play at the top level, 23 at the 2nd, 8 at the third, 3 at the fourth, and 1 at the fifth level. Of the teams who still won't have played at the top level during that time, Peterborough United - relegated from the Championship - finished highest this season. So from that, you can work out the exact season I started watching
