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.

BWF World Championships

The BWF World Championships (formerly known as IBF World Championships, also known as the World Badminton Championships) is a badminton tournament sanctioned by Badminton World Federation (BWF). The tournament offers the most ranking points, together with Summer Olympic Games. The winners will be crowned as the "World Champions" and awarded gold medals. However, it does not offer any prize money.

The tournament started in 1977 and was held once every three years until 1983. However, the IBF faced difficulty in hosting the first two events as the World Badminton Federation (which later merged with the IBF to form one badminton federation) hosted the same tournament a year after the IBF World Championships with the same goals. Started 1985, the tournament became bi-annual and played once every two years until 2005. Starting 2006, the tournament was changed to an annual event on the BWF calendar with the goal to give more chances for the players to be crowned as official "World Champions". However, the tournament will not be held once every four years to give way to the Summer Olympic Games.

World

World is a common name for the whole of human civilization, specifically human experience, history, or the human condition in general, worldwide, i.e. anywhere on Earth or pertaining to anywhere on Earth.

In a philosophical context it may refer to:

In a theological context, world usually refers to the material or the profane sphere, as opposed to the celestial, spiritual, transcendent or sacred. The "end of the world" refers to scenarios of the final end of human history, often in religious contexts.

World history is commonly understood as spanning the major geopolitical developments of about five millennia, from the first civilizations to the present.

World population is the sum of all human populations at any time; similarly, world economy is the sum of the economies of all societies (all countries), especially in the context of globalization. Terms like world championship, gross world product, world flags etc. also imply the sum or combination of all current-day sovereign states.
