What is "oldies"

n. (plural of oldie English)

Oldies is a radio format that concentrates on music from a period of about 25 to 55 years before the present day, primarily from the rock and roll and pop genres.

In the 1980s and 1990s, "oldies" meant the 15 years from the birth of rock n roll to the beginning of the singer-songwriter era of the early 1970s, or about 1955 to 1972, although this varied and some stations chose 1950–1969. After 2000, 1970s music was increasingly included, and early 1980s music is beginning to also be called "oldies", though the term "classic hits" is used to distinguish the "new" oldies (the Generation X oldies) from the "old" oldies (the Baby Boomer oldies).
