World championship

A world championship is generally an international sports competition open to elite competitors from across the world, representing their nations, and winning such an event will be considered the highest or near highest achievement in the sport or contest.

The title is usually awarded through a combination of specific contests or, less commonly, ranking systems (e.g. the ICC Test Championship), or a combination of the two (e.g. World Triathlon Championships in Triathlon). This determines a 'world champion', who or which is commonly considered the best nation, team, individual (or other entity) in the world in a particular field, although the vagaries of sport ensure that the competitor recognised at the best in an event is not always the 'world champion' (see Underdog).

Certain sports do not have a world championship, instead they may organise a world cup competition, or they may organize both. Often, the use of the term cup or championship in this sense is just a choice of words. Some sports have multiple champions because of multiple organizations such as mixed martial arts, boxing and wrestling.

Championship systems

Various forms of competition can be referred to by the term championship.

Title match system

In this system, a competitor has to challenge the current champion to win the championship. A competitor can challenge the current champion after defeating other challengers. This form of championship is used in wrestling, boxing, mixed martial arts and other combat sports.

Tournament system

The term championships (in the plural) is often used to refer to tournament competitions, either using a knockout format, such as at Wimbledon and other championships in tennis, or a mixed format with a group stage followed by knockout rounds, such as used in the European Football Championships.

A variation of the knockout format is the "best-of-X" or series format where two teams face each other for a specified number of times until one team wins the majority of specified games, most of the time the remaining games are not played anymore; only then is the losing team eliminated from contention and the winning team advances to the next level. This format is predominant in American sports such as baseball, ice hockey and basketball, and on test cricket.

League of Legends

League of Legends (abbreviated LoL or just League) is a multiplayer online battle arena, real-time strategy video game developed and published by Riot Games for Microsoft Windows and Mac OS X. It is a free-to-play game supported by microtransactions and inspired by the mod Defense of the Ancients for Warcraft III: The Frozen Throne.

In League of Legends, players assume the role of an unseen "summoner" that controls a "champion" with unique abilities and battle against a team of other players or computer-controlled champions. The goal is usually to destroy the opposing team's "nexus", a structure which lies at the heart of a base protected by defensive structures. Each League of Legends match is discrete, with all champions starting off fairly weak but increasing in strength by accumulating items and experience over the course of the game.

League of Legends was generally well received at release, and grew in popularity in the years since. By July 2012, League of Legends was the most played PC game in North America and Europe in terms of the number of hours played. As of January 2014, over 67 million people played League of Legends per month, 27 million per day, and over 7.5 million concurrently during peak hours.
