In 2007, SBJ and MarketCast launched the Sponsor Breakthrough franchise after multiple leagues claimed their fans were the most brand-loyal and brand-aware consumers in sports. We have fielded 123 league-specific studies, across Major League Baseball, MLS, NASCAR, the NBA, NHL, NFL, PGA Tour (starting in 2008), NCAA (beginning in 2013, although we skipped 2020) and WNBA (starting after the 2021 season).
