There are a few big markets in sports. The first and most obvious one is the major leagues. These are the top level of professional play in each sport and generally consist of the best athletes in the world. Major league teams are typically based in large cities with large fan bases. The other big market in sports is college athletics. College teams also have large fan bases, but they are typically located in smaller towns and cities. College athletes also tend to be less experienced than their pro counterparts. Lastly, there is the amateur market. This consists of all levels of play below the professional ranks including high school, youth leagues, and recreational leagues. Amateur athletes generally have day jobs and do not receive any compensation for their playing time.
