When did alternate rock start?

Answer 1

WLIR radio began an alternative format as early as 1970. By the late 1970's, WLIR was broadcasting a mix of dance, punk, and alternative -- a "new wave" of music. In 1983, soon after music video TV stations became popular, alternative dance rock such as The Police, Men At Work, and David Bowie filled the radio.

In the late 1980's, a heavier, guitar-oriented alternative was developed by bands including Nirvana, Soundgarden, Red Hot Chili Peppers, and Jane's Addiction. In 1990, Alice In Chains joined the list with its first album, Facelift. By 1992, with the introduction of Pearl Jam and the breakthrough of Nirvana, alternative rock swept the nation.
