One of the defining characteristics of Minor Sports Leagues is that they play to smaller crowds of fans. Minor-Leagues.com has compiled a series of posts that provides details of attendance figures.
The United League (IND) was an independent professional baseball league founded in 2006. Its teams were based in Texas and the league merged with the Northern League and the Golden Baseball League to form the North American League from 2011–2012. However, after the North American League folded at the end of the 2012 season, United League was reformed. It dissolved for a second time in January 2015 after playing the 2013 and 2014 seasons.
Below is the fan attendance for the entire league from 2011 to 2012.

The United League recruited college, ex-major and ex-minor league players. Former affiliated-league players that get injured or have other circumstances would also join the ULB as an opportunity to get resigned by major league organizations. Other players consisted of college players that were not drafted into MiLB, but seek the opportunity to be seen by major league scouts and possibly get signed by major league organizations.
