Topic - World Championship

A world championship(s) is the top achievement for any sport or contest. The title is usually awarded by contests, ranking systems, stature, ability, etc. This determines the best nation, team, individual (or other entity) in the world in a particular field. Certain sports do not have a world championship, instead they may organise a world cup, 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. - Source: Wikipedia
