Key contributors[edit]

Todd Storz[edit]

Credit for the format is widely given to Todd Storz, who was the director of radio station KOWH-AM in Omaha, Nebraska in 1951. At that time typical AM radio programming consisted largely of full-service "block programming": pre-scheduled, sponsored programs of a wide variety, including radio dramas and variety shows. Local popular music hits, if they made it on the air at all, had to be worked in between these segments. Storz noted the great response certain songs got from the record-buying public and compared it to the way certain selections on jukeboxes were played over and over. He expanded his domain of radio stations, purchasing WTIX-AM in New Orleans, Louisiana, gradually converted his stations to an all-hits format, and pioneered the practice of surveying record stores to determine which singles were popular each week. Storz found that the more people heard a given song on the radio or from the jukebox, the more likely they were to buy a copy; a conclusion not obvious in the industry at the time. In 1952 he purchased what was then WLAF-AM in Lafayette, Indiana and constructed WAZY-AM/FM which is still the longest running top 40 FM station in existence to this day. In 1954, Storz purchased WHB-AM, a high-powered station in Kansas City, Missouri, which could be heard throughout the Midwest and Great Plains, converted it to an all-hits format, and dubbed the result "top 40". Shortly thereafter WHB debuted the first "top 40 countdown", a reverse-order playing of the station's ranking of hit singles for that week. Within a few years, top 40 stations appeared all over the country to great success, spurred by the burgeoning popularity of rock and roll music, especially that of Elvis Presley. A 1950s employee at WHB, Ruth Meyer, went on to have tremendous success in the early to mid-60's as program director of New York's premiere top 40 station at that time, WMCA.


Storz Broadcasting Company consisted of six AM radio stations, all featuring top 40 in the sixties.

Gordon McLendon[edit]

Although Todd Storz is regarded as the father of the top 100 format, Gordon McLendon of Dallas, Texas, is regarded as the person who took an idea and turned it into a mass media marketing success in combination with the development in that same city of PAMS jingles. McLendon's successful Mighty 1190 KLIF in Dallas, along with his two other Texas Triangle stations, 610 KILT (AM) Houston and 550 KTSA San Antonio, which went top 40 during the mid to late 1950s, soon became perhaps the most imitated radio stations in America. With careful attention to programming, McLendon presented his stations as packages to advertisers and listeners alike. It was the combination of top 40 and PAMS jingles which became the key to the success of the radio format itself. Not only were the same records played on different stations across America, but so were the same jingle music beds whose lyrics were resung repetitively for each station to create individual station identity. To this basic mix were added contests, games and disc jockey patter. Various groups (including Bartell Broadcasters) emphasized local variations on their top 40 stations.


Gordon McLendon would operate approximately a dozen and a half AM, FM and TV stations at various times, experimenting with formats other than top 40 (including beautiful music and all-news).

Rick Sklar[edit]

In the early 1960s Rick Sklar also developed the Top 40 format for radio station WABC in New York City which was then copied by stations in the eastern and mid-western United States such as WKBW and WLS.

Bill Drake[edit]

Bill Drake built upon the foundation established by Storz and McLendon to create a variation called "Boss Radio". This format began in California in early 1961 at KSTN in Stockton, then expanded in 1962–63 to KYNO in Fresno, in 1964 to KGB in San Diego, and finally to KHJ in Los Angeles in May 1965; it was further adapted to stations across the western US. Boss Radio was later broadcast by American disc jockeys as a hybrid format on pirate radio station Swinging Radio England, broadcasting from on board a ship anchored off the coast of southern England in international waters. At that time there were no commercial radio stations in the UK, and BBC radio offered only sporadic top 40 programming. Other noteworthy North American top 40 stations that used the Drake approach included KFRC in San Francisco; CKLW in Windsor, Ontario; WRKO in Boston; WHBQ in Memphis; WOLF in Syracuse, New York; and WOR-FM in New York City. Most listeners identified Boss Radio with less talk, shorter jingles and more music.

Mike Joseph and hot hits[edit]

Mike Joseph's "hot hits" stations of the late 1970s and early 1980s attempted to revitalize the format by refocusing listeners' attention on current, active "box-office" music. Thus, hot hits stations played only current hit songs—no oldies unless they were on current chart albums—in a fast, furious and repetitive fashion, with fast-talking personalities and loud, pounding jingles. In 1977, WTIC-FM in Hartford, CT, dropped its long-running classical format for Joseph's format as "96 Tics" and immediately became one of the top radio stations in the market. The first Joseph station to use the term "hot hits" on the air was WFBL ("Fire 14", which played its top 14 hits in very tight rotation) in Syracuse, NY, in 1979. Then WCAU-FM in Philadelphia switched to hot hits as "98 Now" in the fall of 1981 and was instantly successful. Other major-market stations which adopted the hot hits format in the early 1980s included WBBM-FM Chicago, WHYT (now WDVD) Detroit, WMAR-FM (now WWMX) Baltimore, which we might add was not successful against market leader WBSB B104, KITS San Francisco, and WNVZ Norfolk.

Don Pierson[edit]

Don Pierson took the formats of Gordon McLendon, boss radio and PAMS jingles to the UK in the form of Wonderful Radio London, (a pirate radio ship) and subsequently revolutionized the popular music format. On 14 August 1967 The Marine Offences Act was introduced in the UK and the pirate stations were shut down.


The British Broadcasting Corporation were chosen by the UK government to come up with a station to replace the pirates, and so in 1967 BBC Radio 1 started broadcasting, employing many of the DJ's from the pirate stations (Tony Blackburn, Kenny Everett and John Peel etc.) and obtaining re-sings of the PAMS jingles.


In fact it was Tony Blackburn who played the first pop record on Radio 1, The Move's "Flowers In The Rain".
