MTV shook up reality TV - and introduced fans to the GTL lifestyle (a.k.a. gym, tan, laundry) - in 2009 with the premiere of Jersey Shore. The series quickly made household names out of stars Nicole "Snooki" Polizzi, Vinny Guadagnino, Jenni "JWoww" Farley, Angelina Pivarnick, Paul "DJ Pauly D" DelVecchio, Ronnie Ortiz-Magro, Samantha "Sammi Sweetheart" Giancola and Mike "The Situation" Sorrentino. Deena Nicole Cortese joined the cast during season 3. In 2012, after six seasons, the cast left Seaside Heights, New Jersey, to focus on different projects.
