There are many explanations for this phenomenon . First, baseball is a game with a long history, at least in North America. It was popular with our fathers, our grandfathers, and even our grandfather's fathers. We have all seen grainy film footage of baseball games from the turn of the century, featuring teams that still exist today, wearing uniforms relatively unchanged by the passage of time, and played in a familiar manner. Gazing at the spectators soaking up the sun in the bleachers, it is easy to imagine ourselves in their place, except that the men would no longer be wearing straw hats, white shirts and ties, and the player punching out the loudmouth fan would be Albert Belle rather than Ty Cobb.
Baseball is a link to our past, and by default to our fathers and grandfathers.
It is a constant in a world of mind-boggling change. While the rest of the world has gone from the horse and buggy and butter churn to space travel and computers, baseball is much the same as it has always been. That is not to say that it is untouched by the changes in the world around us. First radio, and then television have brought the game to more people than ever, and vastly increased the potential for commercial exploitation. We are now subjected to billboard sized advertisements on the wall behind the batter at home plate, and ticket and concession prices that are out of reach for many working families.
