Compilation of girl group debuts from 1993 to 2012

A netizen (with a lot of effing time on their hands) kindly compiled a list of the total girl group debuts to date. The chart only counts up to August 2nd, so recent girl groups like EvoL are missing, but it's still a clear indication of the influx the industry is pummeled with each year. 

The category goes from year, group name, member number, debut date, and company name.
