Amateur sports are sports in which participants engage largely or entirely without remuneration. The distinction is made between amateur sporting participants and professional sporting participants, who are paid for the time they spend competing and training. In the majority of sports which feature professional players, the professionals will participate at a higher standard of play than amateur competitors, as they can train full-time without the stress of having another job. The majority of worldwide sporting participants are amateurs. Sporting amateurism was a zealously guarded ideal in the 19th century, especially among the upper classes, but faced steady erosion throughout the 20th century with the continuing growth of pro sports and monetisation of amateur and collegiate sports, and is now strictly held as an ideal by fewer and fewer organisations governing sports, even as they maintain the word " amateur " in their titles.
Amateur theatre , also known as amateur dramatics , is theatre performed by amateur actors and singers. Amateur theatre groups may stage plays, revues, musicals, light opera, pantomime or variety shows, and do so for the social activity as well as the artistic side. Productions may take place in venues ranging from the open air, community centres or schools to independent or major professional theatres and can be simple light entertainment or demanding drama. Amateur theatre is distinct from the professional or community theatre simply in that participants are not paid, although this is not always the case, even though the productions staged may be commercial ventures, either to fund further productions, to benefit the community, or for charity. Amateur actors are not typically members of actors' unions, as these organisations exist to protect the professional industry and discourage their members from working with companies which are not signatories to union contracts. Opinions vary on how to define "amateur" in relation to theatre. Technically speaking, an "amateur" is anyone who does not accept, or is not offered, money for their services.
