Funk carioca is different from the funk originated in the US. Starting in 1970, styles like "bailes da pesada," "black soul", "shaft", and "funk" started to emerge in Rio de Janeiro. As time went on, DJs started to look for other rhythms of black music, but the original name did not remain. The term "baile funk" is used to refer to the parties in which funk carioca is played. Funk carioca first emerged and is played throughout the state of Rio de Janeiro, but not only in the city of Rio, like Rio natives like to believe. Funk carioca is mostly appealing to the youth. In the decade of 1980, anthropologist Herman Vianna was the first social scientist to take Funk as an object to study in his masters thesis, which gave origin to the book "O Mundo Funk carioca", which translates to "The Carioca Funk World"(1988). During that decade, funk dances lost a bit of popularity due to the emergence of disco music, a pop version of soul and funk, especially after the release of the film "Saturday Night Fever" (1977) starring John Travolta and with soundtrack of the band Bee Gees. At the time, the then teenager, Fernando Luís Mattos da Matta was interested in the discotheque when listening to the program Cidade Disco Club on Radio City of Rio de Janeiro (102.9 FM). Years later Fernando would adopt the nickname of DJ Marlboro and the radio would be known as the Rio "rock radio".
