Billboard Decade-End is a series of music charts reflecting the most popular artists, albums, and songs in the United States throughout a decade.^[1] Billboard first published a decade-end ranking in the 1980s, based on the magazine reader's votes, with Madonna becoming the Pop Artist of the Decade. In December 1999, Billboard published decade-end lists based on statistical performances on weekly Billboard charts, with Mariah Carey being dubbed the Pop Artist of Decade. Other artists receiving the honor in the following decades are Eminem (2000s) and Drake (2010s).
