In October 2012, "Billboard" significantly changed the methodology for their country, rock, Latin, and rap charts, when it incorporated sales of digital downloads and streaming plays into what had been airplay-only charts. Another change was that rather than measuring airplay only from radio stations of the particular genre, the new methodology measures airplay from all radio formats. This methodology was extended to their Christian and gospel charts in late 2013. These methodology changes resulted in higher positions on the genre charts for songs with crossover appeal to other genres and radio formats (especially pop) at the expense of songs that appeal almost exclusively to core fans of the given genre, which was controversial with those devotees.
