This impressive history of baseball in the smaller towns and cities of the U.S. is divided into three sections. The first covers the years from 1877 to 1920, when the modern game was evolving and the general outlines of major and minor leagues were taking shape; the second treats the period from 1920 to 1950, the golden age of the minors; the third is devoted to the expansion of the majors and the rise of television, both of which all but destroyed the minors, reducing the number of leagues from 59 to 21.
