Madonna

"Come on vogue," Madonna sang in 1990. And they did — and a revolution followed.

Starting her career in 1982 with her first disco-hit "Everybody," Madonna has grown into a true music icon. Dubbed the Queen of Pop and even Queen of Music by some critics, Madonna has a winning formula of raw talent, shrewd marketing and business instincts, loyal fans and an undefined "x-factor." These facets have kept Madonna relevant throughout the years — capable of spotting music trends before they happen. Madonna was at the forefront of ushering in electronic dance music into Top 40 radio. In addition, she has referenced new-age disco and country in contemporary pop music — something no other artist has done.

Madonna is also an actress. Making her first appearance as the protagonist in 1985's Desperately Seeking Susan, Madonna's film career is one of the most critically polarized in the movie industry. Although panned by critics in films like Shanghai Surprise and Swept Away, she was critically lauded and even won a Golden Globe award for her lead performance in 1997's Evita.

Critics consider Madonna to be a barometer for pop culture, advocate for the LGBTQ community and, most importantly, a pop music icon and legend.

Most recently, Madonna performed at the 2012 Super Bowl halftime show. Her performance was the most-watched Super Bowl halftime show in history, with 114 million viewers. Madonna released her 12th studio album MDNA in 2012, followed by a worldwide tour of the same name. Her MDNA Tour was the highest grossing tour of 2012, giving the Queen of Pop two tours in the top-10 highest-grossing tours of all time.
