Following Swift on the all-time winners list is country legend Garth Brooks (with 19), Usher (18), Adele (18) and Whitney Houston (16). Adele won 12 BBMAs in 2012, one in 2013, and another five in 2016 -- including top artist and top Billboard 200 album (for 25).
Justin Bieber increased his tally to 15 in 2016, following a pair of wins at the May 22 BBMAs -- for top male artist and top social media artist. (Since the latter award category began in 2011, Bieber has been the only act to win the category.)
Mariah Carey is next on the list, with 14, followed by R. Kelly (12) and Rihanna (12). The latter artist earned the fan voted chart achievement award in 2016.
Lil Jon has scored 11 wins (which includes six with the East Side Boyz), while Mary J. Blige, Janet Jackson, Eminem, Destiny's Child, Carrie Underwood and 50 Cent are all tied with 10 wins each.
The 10 Best Moments From the 2016 Billboard Music Awards
The Billboard Music Awards began in 1990, and initially aired yearly through 2006. During those years, the Billboard Music Awards' categories and winners were based on Billboard's year-end charts, which are published in December each year. Not all year-end charts were represented on the yearly show. The BBMAs went on hiatus from 2007 through 2010. The BBMAs returned in 2011, on ABC. From 2011 onwards, the show's categories were no longer based on the year-end charts. Instead, they now honor chart performance during a 12-month span of time, roughly running from the charts dated in early April of the previous year to early April of the current year.
