How much did U.S. CD album sales fall between 2000 and 2014?

In the United States, the rise of file-sharing networks and digital piracy significantly impacted the music industry's traditional revenue models. Between 2000 and 2014, annual sales of compact discs (CDs) in the U.S. fell from a peak of nearly 800 million albums to less than 150 million albums.1

While the industry eventually transitioned to digital distribution through platforms like iTunes and Amazon.com, total industry revenue still declined by more than half during that period compared to the year 2000.21
