20 years have passed since the Korean Society for the Sociology of Sport (KSSS) was officially founded as an academic community. If likened to a person, the Twenty Years of the KSSS marks its coming of age. In 1990, when the KSSS was founded, sport science faced its dawning in South Korea. Over the last two decades, KSSS has played a key role in communicating and developing sociological imaginations of sport and discourses on the sociology of sport. As of 2010, the KSSS has 901 members including 67 board members, advisers and advisory members, around 400 members of which pay the annual membership fee. The KSSS has held seminars and workshops of seven or eight times a year in which about 200 participants have had heated discussions and presentations each time. This is a legacy of the process of institutionalizing the Korean sociology of sport. However, behind this ostensible growth and development, the Korean sociology of sport has faced great difficulty and complicated challenge and crisis most likely to be resolved. It is time for us to not only develop creative thenamics of the Korean society, but also promote the suitability of the Korean sociology of sport to reality. We keenly need to make ories most likely to explain diversity and dyan effort to theorise aboriginal sociology of sport based on the social reality and historical development of Korean sport rather than attempts to explain domestic reality in sport by using theories developed from the western countries.
