The document discusses youth sports sponsorship as the next frontier for sports sponsorship investment. It notes that while professional sports leagues are saturated, high school and youth sports represent an untapped market with over 300 million spectators for high school football and basketball alone. Several examples are given of major brands signing "pro-level" sponsorship deals in the high school and youth sports space, such as ESPN's $30.5 million TV deal with Little League Baseball and Farmers Insurance investing $10 million across 18 high school championships.
