Look it's quite simple. Initially there was just The Football League (FL). Then FL split into 1 and 2, soon to be joined by 3S and 3N. The last two metamorphasised into 3 and 4. So now we had 1,2,3,4 - quite simple huh? But no! 1 wanted distance from lightweights 2,3 and 4 and so became "Premier League" (PL) enroute to "Premiership" (P). But P's plan was foiled as 2,3 and 4 simply became 1,2 and 3 respectively thus maintaining the same distance from P! 1 (the erstwhile 2) followed P's elitist lead and became CCC. Again 2 and 3 (previously 3 & 4) became 1 and 2 so completing the transition from 1,2,3,4 to P,CCC,1 & 2 -all of which was merely a series of rebranding exercises!
