Very few popular spectator sports today remain amateur in any sense of the word. In the past, even in cases where payment to players or athletes was forbidden, many sports tolerated what became known as "shamateurism", and even the sports governing bodies turned a blind eye to such practices as the paying of "expenses". More recently, sport has become, in effect, a branch of the entertainment industry, and the elite performers in sports such as swimming, tennis, football and track athletics can expect to become very rich. This worries some people, who complain that the old Olympic ideal has been lost, but the fact is, sport has become more and more professional in the wider sense, not only requiring total dedication from aspiring champions, but also expensive facilities, training and nutritional advice.
