Justin Bieber's tearful return to the VMA stage also generated a great deal of social-media conversation as did host Miley Cyrus and Nicki Minaj, who called Cyrus out after winning a Moonman.

Kanye West's 13-minute, rambling Michael Jackson Video Vanguard acceptance speech was the biggest moment of the 2015 MTV Video Music Awards, according to conversations on Facebook and Twitter.

The rapper finished his remarks by announcing that he would run for president in 2020, part of what drove the moment to generate the most conversations on Twitter, according to worldwide activity three hours before and during the VMAs. West also was the most discussed VMA star on Twitter during that time period.

West touched on a number of topics in his speech, first reflecting on his memorable 2009 interruption of Taylor Swift, who presented West with his award and offered her own variation on his now famous "I'mma let you finish" comments, and apologizing for his past behavior at awards shows. He also acknowledged that he did, as he noted some may have suspected, smoke something before the show.

Justin Bieber's tearful return to the VMA stage, crying after he delivered his first performance on the MTV awards show in five years, also topped both Facebook and Twitter's lists, as the fourth most popular moment based on conversations on the social media platforms. Bieber was also the fourth most-discussed VMA star on Twitter on Sunday night.

Facebook's second most-talked-about moment was Miley Cyrus' trippy, show-ending performance of her new single "Dooo It!" Cyrus was the second most-talked-about VMA star on Twitter on Sunday night. The VMA host was also involved in Facebook's third biggest moment of the night, when Nicki Minaj called Cyrus out for her remarks in a New York Times story after she accepted her Moonman for best hip-hop video. Minaj, who also performed with Swift at the top of the show, was the fifth most-discussed VMA star on Twitter on Sunday night.

Tori Kelly's performance of "Should've Been Us" was the fifth biggest moment from the show on Facebook.

On Twitter, meanwhile, John Legend and Pharrell's performance and Legend, West and Big Sean winning the video with a social message Moonman were the second and third most talked about moments, with Swift's best female video win for "Blank Space" rounding out Twitter's list.

Twitter reported Monday morning that there were 47 million tweets sent worldwide about the VMAs during the show's East Coast, live airing and three hours before the event.
