The 1990s were a decade that saw marketing became more segmented, as MTV gradually shifted away from music videos beginning in 1992 and radio splintered into narrower formats aimed at different niches. However, they are perhaps best known for grunge, gangsta rap, R&B, teen pop; eurodance, electronic dance music, the renewed popularity of punk rock mainly because of the band Green Day (which would also help create a new genre pop punk) and for being the decade that alternative rock became mainstream. U2 was one of the most popular 1990s bands, their groundbreaking Zoo TV and PopMart tours were the top selling tours of 1992 and 1997. Glam metal dies out through its own accord in the music mainstream by 1991. Grunge becomes popular in 1991 because of the success of Nirvana's Nevermind, Pearl Jam's Ten and Soundgarden's Badmotorfinger. Pop punk also becomes popular with such artists as Green Day, Blink-182, Weezer, Social Distortion, The Offspring, Bad Religion, NOFX and Rancid. Other successful alternative acts included Red Hot Chili Peppers, Radiohead, Gin Blossoms, Oasis, Blur, Soul Asylum, Third Eye Blind, Stone Temple Pilots, Faith No More, The Smashing Pumpkins, Live, Everclear, Bush, Alice in Chains and Screaming Trees.
