Professional athletes are distinguished from amateur athletes by virtue of being paid enough to earn a living. Throughout the world, most top female athletes are not paid, and work full-time or part-time jobs in addition to their training, practice and competition schedules. Women's professional sports organizations defy this trend. Such organizations are relatively new, and are most common in very economically developed countries, where investors are available to buy teams, and businesses can afford to sponsor them in exchange for publicity and promotion of their products. Very few governments support professional sports, male or female.
