The ATP began issuing rankings to players beginning from August 1973. Since 1979, at the start of every week, the ATP publishes its rankings of players. Since inception in 1973, 25 different men have risen to the top of the ATP charts and 17 of those 26 have finished the year as Number 1 on at least 1 occasion. The methodology involved to calculate the ranking points is based on performance in 18 tournaments (19 including the Nitto ATP Finals) which include all 4 Grand Slams, all 8 ATP Masters 1000 events, 4 ATP 500 Tour events where the player has performed the best and best two results from ATP 250 Tournaments. For lower ranked players additional ATP 500 Tour and ATP 250 Tournaments may be included along with ATP Challenger Series and Futures Series Tournaments.
