=== Men's tournament structure ===
==== ATP 1000 ====
The [[ATP Masters 1000]] is a group of nine tournaments that form the second-highest echelon in men's tennis. Each event is held annually, and a win at one of these events is worth 1000 ranking points. When the [[Association of Tennis Professionals|ATP]], led by [[Hamilton Jordan]], began running the men's tour in 1990, the directors designated the top nine tournaments, outside of the [[Grand Slam (tennis)|Grand Slam]] events, as "Super 9" events.<ref>{{cite web|url=http://www.itftennis.com/abouttheitf/worldwide/history.asp|title=History of Tennis|access-date=16 March 2008|archive-date=22 March 2010|archive-url=https://web.archive.org/web/20100322195507/http://www.itftennis.com/abouttheitf/worldwide/history.asp|url-status=dead}}</ref> In 2000 this became the Tennis Masters Series and in 2004 the ATP Masters Series. In November at the end of the tennis year, the world's top eight players compete in the [[ATP Finals]], a tournament with a rotating locale. It is currently held in Turin.<ref>{{cite news |url=https://www.theguardian.com/sport/2019/apr/24/atp-finals-turin-london-2021-tennis|title=ATP Finals move to Turin from 2021 signals the end of an era|work=[[The Guardian]]|access-date=1 January 2024}}</ref>

In August 2007 the ATP announced major changes to the tour that were introduced in 2009. The Masters Series was renamed to the "ATP Masters 1000", the addition of the number 1000 referring to the number of ranking points earned by the winner of each tournament. Contrary to earlier plans, the number of tournaments was not reduced from nine to eight and the [[Monte-Carlo Masters]] remains part of the series although, unlike the other events, it does not have a mandatory player commitment. The [[Hamburg Masters]] has been downgraded to a 500-point event. The [[Madrid Open (tennis)|Madrid Masters]] moved to May and onto clay courts, and a new tournament in [[Shanghai]] took over Madrid's former indoor October slot. As of 2011 six of the nine "1000" level tournaments are combined ATP and [[Women's Tennis Association|WTA]] events.<ref>{{cite web|url=http://www.coretennis.net/majic/pageServer/0p0100006b/en/ATP-Tour-2009.html |title=ATP Tour 2009 |publisher=Coretennis.net |access-date=24 May 2010}}</ref>

The third and fourth tier of men's tennis tournaments are formed by the [[ATP Tour 500|ATP 500 series]], consisting of 11 tournaments, and the [[ATP Tour 250|ATP 250 series]] with 40 tournaments.<ref name="season">{{cite web|title=ATP World Tour Season|url=http://www.atpworldtour.com/Tournaments/Tournament-Landing.aspx|publisher=ATP|access-date=2 May 2012}}</ref> Like the [[ATP Masters 1000]], these events offer various amounts of prize money and the numbers refer to the number of ranking points earned by the winner of a tournament.<ref name="Rankings" /> The [[Dubai Tennis Championships]] offer the largest financial incentive to players, with total prize money of US$2,313,975 (2012).<ref>{{cite web|title=Dubai Duty Free Tennis Championships|url=http://www.atpworldtour.com/Tennis/Tournaments/Dubai.aspx|publisher=ATP|access-date=6 May 2012}}</ref> These series have various draws of 28, 32, 48 and 56 for singles and 16 and 24 for doubles. It is mandatory for leading players to enter at least four 500 events, including at least one after the US Open.

==== Challenger Tour and Futures tournaments ====
The [[ATP Challenger Tour|Challenger Tour]] for men is the lowest level of tournament administered by the [[Association of Tennis Professionals|ATP]]. It is composed of about 150 events and, as a result, features a more diverse range of countries hosting events.<ref>{{cite news | url = http://www.atpworldtour.com/Tournaments/Challenger/ABOUT.aspx | title = About the Challenger Circuit | publisher = [[Association of Tennis Professionals]] | access-date = 2 May 2012 | url-status = dead | archive-url = https://web.archive.org/web/20100227095535/http://www.atpworldtour.com/Tournaments/Challenger/ABOUT.aspx | archive-date = 27 February 2010 | df = dmy-all }}</ref> The majority of players use the Challenger Series at the beginning of their career to work their way up the rankings. [[Andre Agassi]], between winning Grand Slam tournaments, plummeted to World No. 141 and used Challenger Series events for match experience and to progress back up the rankings.<ref>{{cite news | url = https://www.espn.com/sports/tennis/wimbledon06/news/story?id=2506393 | title = An appreciation of Andre Agassi | publisher = [[ESPN]], Matt Wilansky | date = 1 July 2006 | access-date=18 March 2008}}</ref> The Challenger Series offers prize funds of between US$25,000 and US$150,000.

Below the Challenger Tour are the Futures tournaments, events on the [[ITF Men's Circuit]]. These tournaments also contribute towards a player's [[ATP rankings]] points. Futures Tournaments offer prize funds of between US$10,000 and US$15,000.<ref>{{cite web|url=http://www.itftennis.com/mens/circuitinfo/index.asp|title=About the ITF Men's Circuit|publisher=[[International Tennis Federation]]|access-date=18 March 2008|archive-date=4 June 2011|archive-url=https://web.archive.org/web/20110604194726/http://www.itftennis.com/mens/circuitinfo/index.asp|url-status=dead}}</ref> Approximately 530 Futures Tournaments are played each year.
