Why do people enjoy baseball?

Baseball is known as "America's Pastime" because it started during the industrial revolution as America grew and expanded across the continental United States.  Baseball is relatively easy to begin playing but extremely difficult to master, which allows for broad appeal and interest.  In addition to the sport gaining popularity there was significant growth in major US cities, where teams would play.  This led to the rise of twenty, thirty and even sixty-thousand seat stadiums where people of all ages could enjoy the game outdoors.  Ultimately helping the sport maintain its popularity and growth to where it is today - a global top 4 sport.
