Classic rock

Classic rock is a radio format which developed from the album-oriented rock (AOR) format in the early 1980s. In the United States, the classic rock format features music ranging generally from the late 1960s to the late 1980s, primarily focusing on commercially successful hard rock popularized in the 1970s. The radio format became increasingly popular with the baby boomer demographic by the end of the 1990s.

Although classic rock has mostly appealed to adult listeners, music associated with this format received more exposure with younger generations of listeners with the presence of the Internet and digital downloading. Some classic rock stations also play a limited number of current releases which are stylistically consistent with the station's sound, or by heritage acts that are still active and producing new music.

The classic rock format evolved from AOR radio stations that were attempting to appeal to an older audience by including familiar songs of the past with current hits. In 1980, AOR radio station M105 in Cleveland, Ohio began billing itself as "Cleveland's Classic Rock", playing a mix of rock music from the mid-1960s to the present. Similarly, WMET called itself "Chicago's Classic Rock" in 1981. In 1982, radio consultant Lee Abrams developed the "Timeless Rock" format which combined contemporary AOR with hits from the 1960s and 1970s.

KRBE (AM), Houston was another early classic rock radio station. In 1983 program director Paul Christy designed a format which played only early album rock, from the 1960s and early 1970s, without any current music or Top 40 material at all. KRBE was the first station to use the term "classic rock" on the air. Classic rock soon became the widely used descriptor for the format, and became the commonly used term for early album rock music by the general public.

In the mid-1980s, the format's widespread proliferation came on the heels of Jacobs Media's (Fred Jacobs) success at WCXR, Washington, D.C., and Edinborough Rand's (Gary Guthrie) success at WZLX, Boston. Between Guthrie and Jacobs, they converted more than 40 major market radio stations to their individual brand of classic rock over the next several years.
