November 29 In Radio History

In 1929...NBC begins use of the chimes.



The NBC chimes came to their familiar configuration and sound after several years of on-air development. They were first broadcast over NBC's Red and Blue networks on November 29, 1929. However, there are disagreements about the original source of the idea. One story is that they came from WSB in Atlanta, Georgia, which allegedly used it for its own purposes until one day someone at NBC's headquarters in New York City heard the WSB version of the notes during a networked broadcast of a Georgia Tech football game and asked permission to use it on the national network.

The company tested the chimes during 1927 and 1928, when it experimented with several possible combinations of notes. The first sequence consisted of the seven notes G-C-G-E-G-C-E. However, since the original NBC chime was an actual set of four-note chimes made by the J.C. Deagan Company, which the announcer would play 30 seconds before the end of every half-hour to signal the end of a program, it was left to the announcers to play this trademark sequence without error, which was unavoidable with such a lengthy cue. The chime sequence was shortened to G-C-G-E and then, on November 29, 1929, the cue was shortened for the final time, and the three well-known notes G-E-C were heard on NBC radio for the first time.

Despite the relative simplicity and efficiency of the new, shorter chime sequence, problems still existed in other musical aspects of the sequence, such as the tempo, rhythm, and volume at which it was played, as well as the musical tone of the set chimes. Therefore the NBC chimes were mechanized in 1932 with a unit that could play the sequence perfectly and consistently. Richard H. Ranger, a former Radio Corporation of America (RCA) engineer who also invented an early form of the modern fax machine, invented the NBC chime machine that generated the notes by means of finely tuned metal reeds that were plucked by fingers on a revolving drum, much like a music box.

The technical purpose of the mechanical chimes was to send a low level audio signal of constant amplitude that would be heard by the various switching stations manned by NBC and AT&T engineers, but not disturb the listening audience. This would serve as the system cue for switching the myriad local stations between the NBC Red Network and NBC Blue Network feeds as scheduled, as well as signalling the pause for local station identification immediately thereafter. In essence, it was the audio equivalent of a traffic signal. Because of fears of offending commercial sponsors by cutting their live network programs off mid-sentence, the mechanized chimes were always rung by an announcer pushing a button in conjunction with the program’s conclusion; they were never set to an automatic timer, although heavy discussions on the subject were held between the Engineering and Programming departments throughout the 1930s and 1940s.

On November 20, 1947, NBC filed with the U.S. Patent and Trademark Office to make the chimes a registered service mark for identification of radio broadcasting services, the first such audible service mark to be filed with that office. Registration was granted on April 4, 1950; the registration number was 0523616, serial number 71541873. This registration expired on November 3, 1992, as NBC Radio became part of broadcasting history. However a separate service mark registration was made in 1971 for identification of television broadcasting services (serial 72349496, registration 0916522). While this registration is still active, the chime was heard for the final time on the NBC television channel in 1976, the 50-year anniversary of the chime; the chime is now used only for various smaller purposes on the network.

The Fourth Chime

The variant sequence B - D + G = G, based on a G-major arpeggio in second inversion, was known as "the fourth chime". An NBC Interdepartment Correspondence memo, dated April 7, 1933, documents the conception and initial purpose of the fourth chime.

The memo states "In anticipation of the Spring and Summer months, when many in key positions will not always be available at home telephones, the following Emergency Call System will go into effect on Monday morning, April 16."

The memo goes on to say that whenever a fourth tone is heard on the network chimes rung at 15-minute intervals, it will indicate that someone on an attached list is wanted. Upon hearing this fourth chime, all personnel on the list are instructed to call in to the PBX operator to ascertain whether or not the Emergency Call is for them. The chime would continue at 15-minute intervals over stations WEAF and WJZ until the wanted person communicated with the PBX operator. The list contained the names of the following NBC executives:

The "fourth chime" was also used to notify affiliates and their employees of pending urgent programming. This variant saw such use during wartime (especially in the wake of the attack on Pearl Harbor) and other disasters, most notably the Hindenburg disaster in 1937. According to NBC historians, the last official use of the "fourth chime" was in 1945, shortly after the end of World War II. However, according to a handwritten note appended to an NBC internal memo originally dated 1964 on the history and usage of the standard chime, this chime variant was used one final time in 1985 to symbolize the merger with GE.



In 1927...Sportscaster and national treasure Vin Scully was born in the Bronx. His 66 seasons with the Dodgers (1950–present) is the longest tenure of any broadcaster with a single team in professional sports history.


In 1941...the passenger ship, "Lurline", sent a radio signal after sighting a Japanese war fleet in the Pacific.


In 1964...Dean "Dino On Your Radio" Anthony debuted on Top40 WMCA 570 AM, New York.  Anthony was one of the famous WMCA jocks from the 1960s, but he spent even more years building WHLI into a fine popular-standards station. He was a host there right up until his death.


In 1969...the Beatles' "Come Together," single went to #1 on Radio.

Gene Rayburn

In 1999...Gene Rayburn, host of the TV game show Match Game and a host on the NBC Radio Weekend Show 'Monitor', died at 81.

Before appearing in television, Rayburn was a very successful actor and radio performer. He had a popular morning drive time radio show in New York City, first with Jack Lescoulie (Anything Goes) and later with Dee Finch (Rayburn & Finch) on WNEW (now WBBR). Radio history pegs Rayburn's pairings with Lescoulie and Finch as the first two-man teams in morning radio.  When Rayburn left WNEW, Dee Finch continued the format with Gene Klavan.

Rayburn later landed the lead in the Broadway musical Bye Bye Birdie when Dick Van Dyke left the production to star in his eponymous classic sitcom The Dick Van Dyke Show.  Listen to an aircheck from 1964 with Rayburn hosting NBC Radio Network's weekend Monitor Show. Click Here.

2001...Singer/songwriter Beatle George Harrison died of lung cancer at the age of 58. Speaking outside his home northwest of London, Paul McCartney said, "I am devastated and very, very sad." Ringo Starr, speaking from Vancouver, British Columbia said, "We will miss George for his sense of love, his sense of music and his sense of laughter."


In 2008...legendary "Boss Radio" programmer, Bill Drake, died of lung cancer. He was 71.

Bill Drake

Born Phillip Yarbrough, he chose his last name from among his relatives' surnames, because it rhymed with "WAKE", the station in Atlanta, where he worked as a programmer and disc-jockey in the late 1950s.  Later, Bartell Broadcasting, who owned WAKE that he had programmed to number one, transferred him to KYA in San Francisco, which also became number one.

It was later at KYNO in Fresno, California that he met Gene Chenault, who became his business partner. Together, the pair developed highly influential radio programming strategies and tactics, as well as working with future "Boss Jocks".

Drake-Chenault perfected the Top 40 radio format, which had been created by Todd Storz, Gordon McLendon and other radio programmers in the late 1950s, which took a set list of popular songs and repeated them all day long, ensuring the widest possible audience for the station's music. Jingles, news updates, traffic, and other features were designed to make Top 40 radio particularly attractive to car listeners. By early 1964, the era of the British Invasion, Top 40 radio had become the dominant radio format for North American listeners.

Drake streamlined the Top 40 format, using modern methods, such as market research and ratings demographics, to maximize the number of listeners. He believed in forward momentum, limiting the amount of disc jockey chatter, the number of advertisements and playing only the top hits, as opposed to less-organized programming methods of the past. Drake created concepts such as 20/20 News and counter programming, by playing music sweeps, while his competitors aired news. Drake-Chenault controlled everything from the specific DJs that were hired, to radio contests, visual logos, promotions and commercial policy. Drake essentially put radio back into the hands of programming, instead of sales. Drake hired the Johnny Mann Singers to produce the Boss Radio jingles, ensuring a bright, high-energy sound that engaged the listener, while providing a bridge from song to song.



After turning around the fortunes of Fresno's KYNO, Drake applied similar tactics to take KGB, from 14th to 1st in San Diego. KGB's owner, Willett Brown, suggested to his fellow RKO board members, that Drake could turn KHJ around.

In the Spring of 1965, Drake-Chenault were hired to turn KHJ in Los Angeles, from a financial and ratings loser into a success. Drake hired Ron Jacobs as program director, Robert W. Morgan in the mornings and "The Real Don Steele" in the afternoons. KHJ quickly jumped from near-obscurity, to the number one radio station in Los Angeles. Although it was criticized, "Boss Radio" moved faster and sounded more innovative than the competition, making it the #1 choice over competitors in Southern California.



Bill Drake also programmed KFRC in San Francisco, WOR-FM in New York, KAKC in Tulsa, WHBQ in Memphis, WUBE (AM) in Cincinnati, WRKO in Boston and 50,000 watt CKLW, in Windsor, Ontario, across the Detroit River from the city of Detroit.
