History
Experimental years

KCBS is considered to be among the world's
first radio stations. It received its first broadcasting station license, as KQW in
San Jose, in early December 1921. However, the original licensee,
Charles Herrold, had begun making audio radio transmissions in 1909, as part of an experimental radio-telephone system, and KCBS has traditionally dated its founding to that year. Herrold's earliest radio work had been largely forgotten until 1959, when
Gordon R. Greb's "The Golden Anniversary of Broadcasting" was published in the ''Journal of Broadcasting''.
On January 1, 1909, Herrold opened the Herrold College of Wireless and Engineering, located in the Garden City Bank Building at 50 West San Fernando Street in San Jose. In order to promote the college, as well as provide practical experience for his students, a radio transmitter (then commonly known as "
wireless telegraphy

") with a large antenna was constructed atop the building. The earliest transmissions used spark-gap transmitters which could only transmit the dots-and-dashes of
Morse code

.
Herrold was among the first to develop a radio transmitter that could also be used for audio transmissions. After limited success with an approach that used "high-frequency" sparks, he later began using a version of an "arc-transmitter" originally developed by
Valdemar Poulsen. Although his primary objective was to create a wireless telephone that could be commercialized for point-to-point use, beginning in July 1912 Herrold also began making regular weekly entertainment broadcasts, with the debut program featuring phonograph records supplied by the Wiley B. Allen company.
Radio communication was initially unregulated in the United States, and at first Herrold used a variety of self-assigned identifiers for his station, including FN and SJN, plus, for audio transmissions, "San Jose calling". The
Radio Act of 1912 established the licensing of stations through the U.S. Commerce Department, and in late 1915 Herrold was issued an Experimental Station License with the
call sign

6XF. Although Herrold reported success in developing his system, his arc-transmitters were low-powered and would only work at

s above 600 meters (frequencies below 500 kHz). The concurrent development of
vacuum-tube technology, which did not have the same limitations, started making arc technology obsolete.
World War I
In April 1917, with the entrance of the United States into
World War I
World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War, was a World war, global conflict between two coalitions: the Allies of World War I, Allies (or Entente) and the Central Powers. Fighting to ...
, the U.S. government took control of the entire radio industry, and it became illegal for private citizens to possess a working radio receiver. In addition, all civilian radio stations were ordered to be dismantled, so for the duration of the conflict Herrold left the airwaves. This wartime government ban on civilian stations was lifted effective October 1, 1919, and in early 1921 Herrold was reissued an Experimental license, again with the call sign 6XF. (He had previously been issued a license for a portable transmitter, with the call sign 6XE.)
During the war impressive strides had been made in vacuum-tube transmitter and receiver design, and Herrold's arc-transmitters were no longer commercially competitive. In 1920 a number of radio stations in the San Francisco Bay area, employing vacuum-tube transmitters, began making regular entertainment broadcasts, most prominently the "California Theater" station,
6XC, set up by

, which began daily service around April 1920. After the war Herrold needed to become familiar with vacuum-tube equipment before he could return to the air. Although some of his co-workers later reported that he resumed regular broadcasts as early as 1919, the oldest documented report of his resumption of broadcasting, presumably over 6XF, dates to early May 1921, with the announcement that the school was inaugurating a Monday and Thursday night schedule consisting of records supplied by "J. A. Kerwin of 84 East Santa Clara street, dealer in phonographs".
KQW (1921–1949)
Effective December 1, 1921, the Department of Commerce issued a regulation that stations making broadcasts intended for the general public now had to hold a Limited Commercial license specifying operation on a wavelength of 360 or 485 meters, and, on December 9, 1921, a broadcasting station authorization with the randomly assigned call letters of KQW was issued in Herrold's name. This license specified operation on the common "entertainment" wavelength of 360 meters (833 kHz), so KQW initially broadcast only during the hours assigned to it under a time-sharing agreement made with the other local broadcasting stations.
Classifying stations according to when they first received a broadcasting authorization under the provisions of the December 1, 1921, regulations, KQW was tied for 6th in the state of California and 16th in the United States. It is the eighth oldest surviving radio station in the United States and tied for 2nd oldest in California, one day behind
KWG in Stockton, and tied with
KNX in Los Angeles. It is also the oldest in the Bay Area; the next-oldest,
KMKY in Oakland, was licensed as KLS on March 10, 1922.
Operation of KQW was financed by the sale of radio equipment by the Herrold Radio Laboratory, but by 1925 the costs had grown. The station was transferred to the First Baptist Church of San Jose, with Herrold kept on as program director. In 1926, station manager
Fred J. Hart bought KQW's license and facilities, eventually buying the station itself in 1930. From 1937 to 1941, KQW served as the San Jose

of the
Don Lee Broadcasting System. During this time its owner was Julius Brunton & Sons, and the station's operations were co-located with KJBS at 1470 Pine Street in San Francisco. Until 1942, it operated as a service of the Pacific Agricultural Foundation to farmers in the
Central Valley.

transmitting frequencies into three classification: Local, Regional, and Clear Channel. KQW's assignment, 1010 kHz, which it had been using since the previous year, was designated a regional frequency. By 1940, KQW had increased its daytime power to the maximum permitted for regional stations, 5,000 watts. In March 1941, under the provisions of the
North American Regional Broadcasting Agreement
The North American Regional Broadcasting Agreement (NARBA, ; ) refers to a series of international treaties that defined technical standards for AM band (mediumwave) radio stations. These agreements also addressed how frequency assignments were d ...
(NARBA), most U.S. radio stations were shifted to new dial positions, so KQW moved to 740.
Under the NARBA provisions, 740 was a Canadian Clear channel, with
CBL (740 AM) (since transferred to FM; the frequency now is utilized by
CFZM using the same technical perimeters) as the frequency's Class I-A primary station. KQW was classified as a Class II secondary station. However, the great distance between the two stations meant that, with the use of a directional antenna, KQW could apply for permission to increase its power to 50,000 watts. In the early 1940s, the San Francisco Bay area affiliate for the
CBS radio network was
KSFO, which, because it operated on a regional frequency, was limited to a power of 5,000 watts. CBS wanted to have a station operating at a full 50,000 watts, and an agreement was initially made for KQW and KSFO to swap frequencies — KSFO to 740 and KQW to 560 — after which KSFO would upgrade to 50,000 watts. However, this plan fell through because CBS also wanted to own the Bay Area affiliate, and the owners of KSFO were not willing to sell. Due to this rebuff, in 1942 CBS transferred its affiliation from KSFO to KQW, with an option to eventually purchase KQW. The station staff moved to a CBS-owned studio located at the
Palace Hotel. For all intents and purposes, it was now a San Francisco station. However, it was still licensed to San Jose, so an announcer was posted at the transmitter site to provide the required "KQW, San Jose" legal IDs.
The beginning of KCBS (1949–1995)
CBS exercised its option to buy KQW in 1949, changing the station's call letters to KCBS. In 1951, KCBS signed on for the first time from the four-tower 50,000-watt facility at
Novato that had originally been intended for KSFO. KCBS's
city of licence was also officially changed from San Jose to San Francisco.
In 1968, KCBS became one of the first
all-news stations in the country, as CBS was converting many of its radio stations nationwide to the format, developed at
WCBS in New York City. KCBS already had a long history in news dating back to
World War II

, when it was the center of CBS' newsgathering efforts in the
Pacific Theater. In 1971, KCBS moved its studios to the 32nd floor of
One Embarcadero Center. Notable anchors and reporters who became popular during the early "Newsradio" era included Al Hart, Frank Knight,
Dave McElhatton (whose KCBS tenure dated to the early 1950s, including hosting a popular morning show on the station before the all-news format was implemented; McElhatton moved to KPIX-TV in 1977, where he was a highly popular and trusted lead anchorman until his retirement in 2000), Ray Hutchinson (KCBS' first business anchor under the all-news format, delivering his updates from the floor of the
Pacific Stock Exchange),
Ken Ackerman (who began on the station in 1942, later hosting KCBS' version of ''Music 'Til Dawn'' and eventually becoming a news anchor under the all-news format, serving until his retirement in 1995), Bob Price, a longtime business anchor and editor for KCBS who worked for over 20 years at the radio station, anchored from the Pacific Stock Exchange until his retirement on November 5, 2009.
Throughout its early history, KCBS also broadcast local sports. As early as 1949, KCBS broadcast
Stanford University football games. Upon converting to its all-news format in 1968, KCBS stopped broadcasting Stanford sports, whose broadcasts moved to rival
KSFO.
In 1985, KCBS signed a three-year contract to broadcast Stanford football and men's basketball.
In 1992, Stanford dropped KCBS in favor of
KFRC-AM in 1992 in order to find a station that would devote more airtime to discuss Stanford sports than KCBS could with its all-news format.
From 1980 to 1986, KCBS broadcast
San Jose State football.
However, KCBS carried most San Jose State games on tape delay in the
1986 season due to conflicts with Stanford games.
KCBS did not renew its contract with San Jose State after it expired, and San Jose station
KHTT won San Jose State broadcast rights beginning in 1987.
From 1981 to 1986, KCBS was the flagship station for the

bought CBS, bringing the Bay Area's oldest radio station under common ownership with its oldest television station, KPIX-TV Channel 5, which Westinghouse had purchased from Associated Broadcasters in 1954. In May 2006, KCBS and KPIX-TV moved their
news bureau in San Jose to the Fairmont Tower at 50 West San Fernando Street. This was, coincidentally, the location of Charles Herrold's original broadcasts. CBS management was unaware of the San Fernando Street address' history when the move was planned. However, once informed that this was the birthplace of KCBS, they recognized this at the bureau's opening celebration.

In mid-March 2005, KCBS, along with nearly all of the other all-news stations owned by

simulcasting its full schedule over co-owned KFRC-FM (106.9) and that station's HD1 digital sub-channel. (KFRC-FM's previous "classic hits" format was moved to 106.9 HD2.) The stations' microphone flag now displays "740" on two sides of the cube, and "106.9" on the other two. In 2011 the stations adopted the joint branding of "All News 106.9 and AM 740, KCBS". KFRC-FM did not change its call letters because the KCBS-FM call sign was already in use by a CBS owned station in Los Angeles on 93.1 FM. Additionally, CBS wanted to keep another Bay Area station from trading on the KFRC calls' legacy in the area.
Sale to Entercom
On February 2, 2017, CBS Radio announced it would merge with
Entercom. While CBS shareholders retained a 72% ownership stake in the combined company, Entercom was the surviving entity, separating KCBS radio from KPIX.
The merger was approved on November 9, 2017, and was consummated on November 17. As part of the agreement with CBS, Entercom was given the rights to use the brand and trademarks for KCBS (along with sister stations
KCBS-FM in Los Angeles, and
WCBS-FM in New York City) for a 20-year period, after which Entercom (or succeeding entity) will be required to relinquish these call signs. On March 30, 2021, Entercom changed its name to Audacy.
Pioneer station status
One of the conditions of Herrold's sale of KQW in 1925 was that the new owners include, in the sign-on announcement, the following: "This is KQW, pioneer broadcasting station of the world, founded by Dr. Charles D. Herrold in San Jose in 1909".
Although there are reports that Herrold was making experimental audio transmissions as early as 1909, the best evidence is that it wasn't until July 1912 when he began making regularly scheduled broadcasts. These weekly programs are generally accepted as being the first regular entertainment broadcasts made by radio. More contentious is whether KCBS can be considered the oldest radio station in continuous service, due to the fact that, following the end of World War I, Herrold did not resume regular broadcasting until May 1921. (Other candidates for oldest U.S. radio station include

In 1945, stations WWJ and KDKA held competing 25th anniversary celebrations, both claiming to be the oldest "commercial radio station". Later that same year, KQW prepared and broadcast "The Story of KQW". The program made the claim that KCBS is the oldest radio station, predating by eleven years both WWJ and KDKA. This broadcast included a brief recorded statement by Herrold, made just before his 70th birthday. All three of these stations, WWJ, KDKA and KCBS, eventually came under the common ownership of CBS Radio and remain sister stations under the ownership of Audacy.
