Entertainment and Sports Law relate to the laws governing such things as sports and recording contracts, broadcast rights, sports safety issues, and some issues relating to intellectual property and copyright law. The primary concern of artists and entertainers is the creation of their art. But creating art should not be their only concern, because making a living as an artist or entertainer also is a business. Likewise, while the primary concern of professional athletes is playing the game, athletes also must be businesspersons. Artists, entertainers and athletes must understand the legal aspects of the business relationships they enter into with agents, teams, sponsors, production companies, book publishers, managers, music clubs and record companies. They also should be concerned with laws that regulate any business relationships they form. An artist, entertainer or athlete who ignores these laws or fails to get important business relationships defined in writing is likely to encounter problems as his or her career advances.
