Why were sports becoming more popular both at the high school and college level and at the professional level?

Sports were becoming more popular at both the high school and college level, as well as professionally, due to the rise of organized competitions, increased media coverage, and the growing influence of mass culture. The establishment of leagues and tournaments provided structure and excitement, while radio and television broadcasts made games accessible to broader audiences. Additionally, the post-World War II economic boom fostered a culture of leisure and entertainment, with sports serving as a unifying social activity in communities. This combination of factors contributed to the widespread enthusiasm for athletics across various levels.
