Top 40 is a music industry shorthand for the currently most-popular songs in a particular genre. When used without qualification it refers to the best-selling or most frequently broadcast popular music. The term is derived from record music charts, a few of which traditionally consist of a total of 40 songs. Top 40 is also an alternative term for the radio format of such music, also known as Contemporary hit radio.

History[edit]

The term "Top 40" for a radio format appeared in 1951.[1] The Top 40, whether surveyed by a radio station or a publication, was a list of songs that shared only the common characteristic of being newly released. Its popularity coincided with the rapid changes in recording technology in the 1950s and 1960s. In 1954, the recording industry agreed upon a standard recording format for higher fidelity music, so any new record player could play any new record. Also in that year, new single records were released on 45 rpm records, and the Top 40 thereafter became a survey of the popularity of these records (and their airplay on the radio).

By the late 1980s and the early 1990s, the 45 rpm record would decrease in popularity and other means would be used to evaluate the popularity of new songs, such as cassette-single, CD single, and digital MP3/AAC sales (plus radio airplay). Some disc jockeys of Top 40 and similar format programs have been implicated in various payola scandals.
