The Seattle Seahawks played their first-ever regulation NFL game September 12, 1976. There was a roster of talented players that Seattle fans soon embraced. While players and coaches have come and gone over the years, fan support has always been strong. The crowds that fill CenturyLink Field are such an integral part of the team's success that on December 15, 1984, the Seahawks retired the number 12 in honor of their fans, the 12th Man.

In 2006, the Seahawks made their first-ever Super Bowl appearance.

The Seattle Seahawks Charitable Foundation was founded in 1995 to promote the healthy social, emotional, intellectual, and physical development of youth by enhancing opportunities for participation in sports and fitness activities.

The Foundation sponsors the Spirit of 12 Partners Program, a collaboration among Seattle youth service organizations, the Seahawks, and The Paul G. Allen Family Foundation. Under this program, community-based nonprofits distribute the Seahawks game day program during the team's home games. Each partner keeps 100% of the proceeds, which is matched by The Paul G. Allen Family Foundation.
