Sports marketing as a concept has established itself as a branch of marketing over the past few decades; however, a generally accepted definition does not exist. Academicians Kaser and Oelkers (2005, p. 9) define sports marketing as 'using sports to market products'. It is a specific application of marketing principles and processes to sport products and to the marketing of non- sports products through association with sport.
