When did it start? Like a few on here my first times of watching the 50 over game as a kid in the early 80s is 5 matches before a test series with the same side as it was going to be in the test matches. When did all this start to change? Was the 1983 England team more or less the test team, same with 1987? Also not just from a England perspective of course. Which countries were the first to adapt to what we see now in the modern format of the game
