The vast majority of people who play sport are amateurs who take part for a variety of reasons relating to their social lives, health, and for the pure pleasure of it. ‘Amateurs and professionals’ describes the difference between amateurism and professionalism in sport that emerged in the 19th century. The amateur was someone who stood for a clearly outlined set of values and money was seen as a corrupting force. Sports such as horse racing, cricket, golf, and boxing, which had organized themselves in the 18th century, became professionalized and commercialized rapidly. Others fought professionalism for much longer—rugby union only abandoned its amateur-only rule in 1995.
