- Top 40
The Top Forty or Top 40 is a music industry shorthand for the currently most-popular songs in a particular genre. When used without qualification, it typically refers to the best-selling or most frequently broadcast
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 fifties and sixties. 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 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. Tape recording had become perfected, allowing artists more freedom as they composed songs, especially novelty songs .
In the heyday of Top 40, between two and seven songs would enter and leave the survey. Chart runs could range from a week or two, to several months. Generally, only the biggest hits of a given year would remain on the charts for fifteen weeks or more. Fans would associate seasons and semesters with the songs they remembered from the juke boxes or the radio.
contests, listener dedications, news updates, traffic reports, and other features were designed to make Top 40 radio particularly attractive to listeners. By early 1964, the era of the British Invasion, Top 40 radio had become the dominant radio format for North American listeners and quickly swept much of the Western world, being brought into the United Kingdomby offshore stations such as Wonderful Radio London, and later adopted by BBC Radio 1. Some stations tried "extremely" "tight" radio playlists, going with the Top 30 or even the Top 20 songs, but most industry experts felt that listener fatiguewould set in more quickly with smaller lists. Top 40 quickly became the dominant radio format of the 1960s, 1970s, and 1980s, although as music formats began to fracture, most stations began to specialize in certain restricted kinds of popular music, usually playing specific types of rock such as mainstream, the so-called " soft rock", or other music charted by radio industry trade publications.
Other lists of hit songs may include a different number of entries, such as a "Top 50" or "Top 100".
By the late eighties and early nineties, the 45 rpm record would become extinct and other means would be used to evaluate the popularity of new songs. As a result, chart runs for songs tend to be longer than they were in the sixties and seventies.
The current top songs are tracked by a variety of trade publications, such as:
