Professional wrestling championship
A championship or title in professional wrestling is a recognition promoted by professional wrestling organizations. Championship reigns are determined by professional wrestling matches, in which competitors are involved in predetermined rivalries. These narratives create feuds between the various competitors, which cast them as villains and heroes. The bookers in a company will place the title on the most accomplished performer, or whom they believe will generate fan interest in terms of event attendance and television viewership.
