In 2009 the award for Best Dancing was again eliminated from the VMAs, but it was revived again in 2010 as Best Dance Music Video.  The following year, though, the award was once again absent from the category list.  Once again, the award was revived in 2012, this time under the name of Best Electronic Dance Music Video, celebrating the rise in popularity of EDM throughout the year.  It was again eliminated for the 2013 awards.  On July 17, 2014, MTV brought the category back, this time renaming it the MTV Clubland Award for the 2014 Awards.

MTV Video Music Brazil: The MTV Video Music Brazil awards (originally Video Music Awards Brazil), more commonly known as VMB, were MTV Brasil's annual award ceremony, established in 1995.  MTV viewers picked the winners for most categories since 2001.  Unlike in the MTV Video Music Awards, the most important category at the MTV Video Music Brazil was the Viewer's Choice, not the Video of the Year; both of these categories merged in 2005.  In 2007, the awards have faced a major rebranding, with several categories extinguished (most notably the specific genre divisions) and even the trophies' design changed; from this year on, the awards were no longer focused on music videos, but on the artists, and the most important category became the Artist of the Year.

The last of this award was given out in 1998 to Green Day for their song "Good Riddance (Time of Your Life)".  After the award's discontinuation, artists and videos who would have normally been eligible for this award became eligible for other genre categories, including Best Rock Video.
