Over at my Forbes blog I have spent the last three weekdays rolling out a three-part series explaining why Seattle Sounders FC have achieved record US attendance figures. The first post explains the unique history of soccer in the Seattle area, and how the NASL Sounders built a special connection between the city and the Sounders brand. The second post tells the story of how semiprofessional players kept the sport alive in the city without the draw of top flight soccer, and how the Sounders FC organization laid the groundwork for success before the team played its first game. The third-and-final post provides an explanation of how Sounders FC found unique ways to appeal to both old school Sounders fans and newer fans of the international game. It also attempts to answer the question of “can this be replicated elsewhere?” Have a look if you're interested in learning more about how the best-attended US soccer club achieves such success.
