Editing Promotion and relegation (section)

== Use in other competitions ==
Promotion and relegation has been used in several [[eSports]] leagues. [[Blizzard Entertainment]]'s video game ''[[StarCraft II]]'' has a "ladder" that uses a promotion and relegation system, where individual players and pre-made teams can be promoted and relegated during the first few weeks of a league season, which generally lasts around 11 weeks, with promotion and relegation taking place based on a skill rating, which is in turn based on wins and losses.<ref>{{cite web|url=http://us.battle.net/sc2/en/blog/10117387|title=StarCraft II Ladder, League, and Season FAQ|website=StarCraft II}}</ref> However, this form of [[matchmaking (video games)|matchmaking]] is not typically used for StarCraft II e-sports tournaments, which have various kinds of structures depending on the organizer, the most important being the [[ESL Pro Tour]] {{as of|lc=on|2021}}. Most professional ''[[League of Legends]]'' leagues like the [[League of Legends Championship Series]] and [[League of Legends Champions Korea]] used a promotion and relegation system, although the LCS moved away from this in 2018 for North America LCS and 2019 for the European LCS (which was renamed to the [[League of Legends European Championship]]), while the LCK moved away from the system in 2020. As of 2023, the [[Pacific Championship Series]] and [[Liga Latinoamérica]] are the only top-tier professional League of Legends leagues to have promotion and relegation; North America's second-tier league, the North American Challengers League, also has promotion and relegation, as do the various regional leagues in Europe, but not with the top divisions.

The ''[[Counter-Strike]]'' Majors used a similar system where in the top eight finishers of one of the bi-annual Majors are designated with the "Legends" seed and automatically qualified for the next Major tournament. The best six eliminated teams in the second stage (known as ''New Legends Stage'') of the Major would play a "qualifying" stage (known as ''New Challengers Stage'') with another ten teams from the Minors qualifying tournaments in order to compete at the ''New Legends Stage''. Starting in 2020, however, this was changed to a Regional Major Ranking system, at first a points-based system which was used for ESL One Rio 2020 and [[PGL Major Stockholm 2021|PGL Stockholm 2021]] (The top rankings from the ESL One Rio 2020 RMRs were turned into PGL Stockholm 2021 points once IEM Rio was cancelled due to the [[COVID-19 pandemic]]) and then a series of offline qualifiers starting with [[PGL Major Antwerp 2022|PGL Antwerp 2022]], in which the teams from the ''Legends Stage'' (Now known as the ''Elimination Stage'') from the previous Major automatically qualify for their RMRs and are joined by online qualifiers.

From 1993 until 2003, the [[Eurovision Song Contest]] used various systems of relegation to reconcile the number of countries wishing to participate (approximately 30 at the time) with the number of performances allowed considering time constraints of a live television program. The addition of a semi-final in 2004 allowed for more than 26 songs, but in 2008 automatic qualification of the previous year's top 10 to the final was removed.

In Brazilian carnival's [[samba school]] contest, a similar system is adopted, with the schools from lower divisions, or "groups", able to be promoted into the highest tier, being currently called the "Special Group" (''Grupo Especial''). Schools parade in order of groups and ranking from last year contest, with the better ranked inside a group and the higher-tier groups having the privilege of going latter (this means the team has the opportunity of fixing issues with costumes and allegorical floats as well as more rehearsal time). The number of promoted and relegated schools, four until 1997, has been diminishing as time passes, becoming two from 1998 to 2007 and being only one nowadays. There has never been an official reason for that, but it is a fact that the relegated schools have more to lose nowadays, such as access to the [[Cidade do Samba]] ("Samba City") facilities. There have been reported several interferences on the contest's final result, especially when traditional schools are involved.<ref>{{Cite web|url=https://agenciabrasil.ebc.com.br/cultura/noticia/2017-03/escolas-de-samba-do-rio-decidem-suspender-rebaixamento-em-2017|title = Liesa suspende rebaixamento de escolas de samba neste ano|date = March 2017}}</ref><ref>{{Cite web|url=https://g1.globo.com/rj/rio-de-janeiro/noticia/2020/09/12/mp-apura-se-crivella-agiu-para-impedir-o-rebaixamento-de-duas-escolas-no-carnaval-de-2018.ghtml|title=Crivella teria interferido no resultado do carnaval de 2018, segundo investigação do Ministério Público|date=12 September 2020 }}</ref>
