Mainstream Top 40

Mainstream Top 40 (also called Pop Songs on billboard.com and sometimes referred to as Top 40/CHR) is a 40-song music chart published weekly by Billboard Magazine which ranks the most popular songs being played on a panel of Top 40 radio stations in the United States. The rankings are based on radio airplay detections as measured by Nielsen Broadcast Data Systems (Nielsen BDS). Arbitron refers to the format as contemporary hit radio (CHR).

History

The chart debuted in Billboard Magazine in its issued date October 3, 1992, with the introduction of two Top 40 airplay charts, Mainstream and Rhythm-Crossover. Both Top 40 charts measured "actual monitored airplay" from data compiled by Broadcast Data Systems (BDS). The Top 40/Mainstream chart was compiled from airplay on radio stations playing a wide variety of music, while the Top 40/Rhythm-Crossover chart was made up from airplay on stations playing more dance and R&B music. Both charts were "born of then-new BDS electronic monitoring technology" as a more objective and precise way of measuring airplay on radio stations. This data was also used as the airplay component for Hot 100 tabulations.

Top 40

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

The term "Top 40" for a radio format appeared in 1960. 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 introduction coincided with a transition from the old ten-inch shellac 78 rpm record format for single "pop" recordings to the seven-inch vinyl 45 rpm format, introduced in 1949, which was outselling it by 1954 and soon replaced it completely. The Top 40 thereafter became a survey of the popularity of 45 rpm singles and their airplay on the radio. Some nationally syndicated radio shows, like American Top 40, featured a countdown of the forty highest ranked songs on a particular music or entertainment publication. Although such publications often listed more than 40 charted hits, such as the Billboard Hot 100, time constraints allowed for the airing of only forty songs; hence, the term "top 40" gradually became part of the vernacular associated with popular music.

American Top 40

American Top 40 (commonly abbreviated to AT40) is an internationally syndicated, independent song countdown radio program created by Casey Kasem, Don Bustany, Tom Rounds and Ron Jacobs. The program is hosted by Ryan Seacrest, who took over the program from Kasem upon his 2004 departure. It is currently presented as an adjunct to Seacrest's weekday radio program, On Air with Ryan Seacrest.

Originally a production of Watermark Inc. (later a division of ABC Radio, now Cumulus Media Networks), AT40 is now distributed by Premiere Networks in the United States, Canada, Australia, the Philippines, Singapore, China, India, the United Kingdom, Malaysia and several other territories worldwide. It can also be heard on both the iHeartRadio application and the AT40 Mobile application on mobile smartphones and tablets as well as on Xbox 360 and Xbox One consoles.

Co-creator Casey Kasem hosted the original AT40 from its inauguration on July 4, 1970 until August 6, 1988 and returned to host the revived version from March 28, 1998 to January 3, 2004 (for much of the interim, he hosted the competing Casey's Top 40). AT40's other two regular hosts have been Shadoe Stevens, who replaced Kasem on the original AT40 and hosted until its 1995 cancellation, and the aforementioned Ryan Seacrest. Currently, AT40 with Seacrest airs in two different formats, with one distributed to Contemporary Hit Radio (Top 40) stations and the other to Adult Contemporary (formerly Hot Adult Contemporary) stations (which were previously served by two different Kasem-hosted shows; see below). There is no differentiation between the Top 40 and AC versions of AT40 made on air. Kasem is still heard in two weekly replays of vintage shows from the '70s and '80s, respectively.
