cube, and "106.9" on the other two. In 2011 the stations adopted the joint branding of "KCBS All News 740 AM and 106.9 FM." (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). In mid-September 2010, KCBS Radio's website was merged with that of KPIX and their sister radio properties in the San Francisco market under the "CBS San Francisco" banner. 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. On March 30, 2021, Entercom changed its name to Audacy. As part of the agreement with CBS, Entercom was given therights to use the brand and trademarks for KCBS-AM along with sister stations KCBS-FM in Los Angeles and WCBS-AM and WCBS-FM in New York City for a 20 year period after which Entercom (or succeeding entity) will be required to relinquish using those call-letters.

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 8MK / WWJ in Detroit, which began regular broadcasts in August 1920; WOC in Davenport, Iowa, which traces its origin to station 9BY, beginning regular broadcasts around September 1920; 9ZAF/KLZ in Denver, with nightly concerts beginning in October 1920; and 8ZZ/KDKA in Pittsburgh, which began operating on November 2, 1920.) In 1945, stations WWJ and KDKA held competing 25th anniversary celebrations, both claiming to be the oldest "commercial
