 She reissued her first album as "The Fame Monster" (2009), preceded by a music video for the lead single "Bad Romance", which won a Grammy Award for Best Music Video and seven MTV Video Music Awards, including Video of the Year in 2010.
 The following year, Jonas Åkerlund directed the music video for "Telephone"—a continuation of "Paparazzi"—which was shot as a short film.

The MTV Video Music Award for Best Dance Video was first awarded in 1989, and it was one of the original four genre categories that were added to the MTV Video Music Awards that year.
 With a revamp of the awards in 2007, the category was cut out along with several others, yet it returned for the 2008 awards, where it was given a new name: Best Dancing in a Video.
 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.
 The pattern of awarding the moonman every other year continued in 2016 where the award was renamed Best Electronic Video.

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.
 However, the Video of the Year category existed to award the best music video.

 For the video of "You Belong with Me" she won Best Female Video at the 2009 MTV Video Music Awards.
 During her acceptance speech, she was interrupted by rapper Kanye West, which sparked controversy and received much media attention.

 By 2001, the VMA had become a coveted award.
