Over 8 million spectators filled the stadiums to watch professional baseball games this season. This is the first time Korea's professional baseball league has reached the mark in its 35-year history.

The record turnout has been attributed to a combination of factors including the expansion to a 10-team league and the construction of new stadiums.

But most notably, it is due in great part to the growth in the number of female spectators. According to ticketing website Ticketlink, females accounted for 43 percent of all buyers last year.
