Oldies is a term for musical genres such as pop music, rock and roll, doo-wop, surf music (broadly characterized as classic rock and pop rock) from the second half of the 20th century, specifically from around the mid-1950s to the 1980s. After 2000, 1970s music was increasingly included, and music from the 1980s to the 2000s is beginning to also be called "oldies", though the term "classic hits" is used to distinguish the "new" oldies from the "old" oldies.[citation needed]
