When we started The A Cappella Blog in 2007, the a cappella world was different.
No major studio motion pictures (though Pitch Perfect, the book felt like a milestone). There were no a cappella TV shows. You could go to an ICCA quarterfinal and see as few as five groups compete. And while a handful of a cappella videos had achieved some notoriety, very, very few had achieved viral status.
What a difference six years can make.
