The first documented use of the term "mixed martial arts" was in a review of UFC 1 by television critic Howard Rosenberg in 1993. The term gained popularity when newfullcontact.com, then one of the largest websites covering the sport, hosted and republished the article. The question of who actually coined the term is subject to debate. - A combat sport, or fighting sport, is a competitive contact sport with one-on-one combat. Determining the winner depends on the particular contest's rules. In many fighting sports, a contestant wins by scoring more points than the opponent or by disabling the opponent. Boxing, wrestling, Muay Thai, Tae Kwon Do, Judo, Brazilian Jiu-jitsu, Sambo, and Mixed Martial Arts are examples of combat sports. - Boxing is a combat sport in which two people wearing protective gloves throw punches at each other for a predetermined set of time in a boxing ring. - Featherweight is a weight class in the combat sports of boxing, kickboxing, mixed martial arts and Greco-Roman wrestling. - Greco-Roman (US) or Graeco-Roman (UK) wrestling is a style of wrestling that is practiced worldwide. It was contested at the first modern Olympic Games in 1896 and has been included in every edition of the summer Olympics held since 1908. Two wrestlers are scored for their performance in two three-minute periods, which can be terminated early by a pin (or fall). This style of wrestling forbids holds below the waist; this is the major difference from freestyle wrestling, the other form of wrestling at the Olympics. This restriction results in an emphasis on throws because a wrestler cannot use trips to take an opponent to the ground, or avoid throws by hooking or grabbing the opponent's leg. Given the paragraphs above, decide what entity has the relation 'occupation' with 'boxer'.
