Marshall Bruce Mathers III (born October 17, 1972), known professionally as Eminem (; often stylized as EMINƎM), is an American rapper, songwriter, record producer, record executive, film producer, and actor. He is consistently cited as one of the greatest and most influential artists of all time in hip hop, with Rolling Stone placing him in its list of the 100 Greatest Artists of All Time and labeling him the "King of Hip Hop".After his debut album Infinite (1996) and the extended play Slim Shady EP (1997), Eminem signed with Dr. Dre's Aftermath Entertainment and subsequently achieved mainstream popularity in 1999 with The Slim Shady LP, which earned him his first Grammy Award for Best Rap Album. His next two releases, 2000's The Marshall Mathers LP and 2002's The Eminem Show, were worldwide successes, with each being certified diamond in U.S. sales and both winning Best Rap Album Grammy Awards—making Eminem the first artist to win the award for three consecutive LPs. They were followed by Encore in 2004, another critical and commercial success. Eminem went on hiatus after touring in 2005 partly due to a prescription drug addiction. He released Relapse in 2009 and Recovery in 2010. Both won Grammy Awards and Recovery was the best-selling album of 2010 worldwide, the second time he had the international best-selling album of the year (after The Eminem Show). Eminem's eighth album, 2013's The Marshall Mathers LP 2, won two Grammy Awards, including Best Rap Album; it expanded his record for the most wins in that category and his Grammy total to 15. These were followed by 2017's Revival and 2018's Kamikaze, the latter being the best-selling hip hop album of 2018.In addition to his solo career, Eminem is an original member of the Midwest hip hop groups Soul Intent and D12. He is also known for his collaborations with fellow Detroit-based rapper Royce da 5'9"; the two are collectively known as Bad Meets Evil. Eminem has developed other ventures, including Shady Records, with manager Paul Rosenberg, which helped launch the careers of artists such as 50 Cent. Eminem has also established his own channel, Shade 45, on Sirius XM Radio. In November 2002, he starred in the hip hop film 8 Mile playing a semi-fictionalized version of himself, which won the Academy Award for Best Original Song for "Lose Yourself", becoming the first rap artist to ever win the award. Eminem has made cameo appearances in the films The Wash (2001), Funny People (2009), and The Interview (2014), and the television series Entourage (2010). Eminem is the best-selling artist of the 2000s in the United States. Throughout his career, he has had nine number-one albums on the Billboard 200 and five number-one singles on the Billboard Hot 100. He is the only artist to have nine albums consecutively debut at number one on the Billboard 200. With over 230 million records sold globally, Eminem is among the world's best-selling artists of all time.

He is also known as M&M, EMINƎM, Slim Shady, Marshall Mathers, Marshall Bruce Mathers III, B-Rabbit, Em, Double M and King of Hip Hop.
