At the end of each year, "Billboard" tallies the results of all of its charts, and the results are published in a year-end issue and heard on year-end editions of its "American Top 40" and "American Country Countdown" radio broadcasts. Between 1991 and 2006, the top single/album/artist(s) in each of those charts was/were awarded in the form of the annual Billboard Music Awards, which were held in December until the awards went dormant in 2007. The awards returned in May 2011.
