Long Description:
"KNBR is an AM radio station licensed to San Francisco, broadcasting on a clear channel at 680 kHz from transmitting facilities near Belmont, California. KNBR's non-directional 50,000-watt class-A signal can be heard throughout much of the western United States and as far west as the Hawaiian Islands at night. For several decades, KNBR enjoyed a long history as the flagship station of NBC's West Coast radio operations." (visit link)

"KNBR history

KNBR began broadcasting on April 17, 1922 as KPO, a 100-watt station owned by the Hale Brothers department store. In 1925, the San Francisco Chronicle newspaper bought half-interest in the operation.[4] Originally located in the department store at Market and 5th (now the site of Nordstrom), its horizontal wire antenna on the roof was so efficient, it immediately attracted the attention of audiences all over the Pacific Coast.

In 1927, KPO became an affiliate of the new NBC radio network. In 1933, KPO was sold to NBC's parent company, the Radio Corporation of America (RCA), and its operation was consolidated into that of its co-owned KGO at the Hunter-Dulin Building, 111 Sutter Street. From there, NBC operated its West Coast network, feeding dozens of stations and operating a news bureau to serve NBC. As NBC's flagship station on the West Coast, it had a full-time orchestra, five studios, and produced many live shows. During the rise of Hollywood, NBC's radio operation was moved to Los Angeles.

In 1941, just before World War II, NBC constructed Radio City at 420 Taylor Street, considered one of the best radio facilities built during radio's golden age. However, with the network control having been moved to Los Angeles, the San Francisco NBC building was never fully utilized. (Later, the building housed KBHK-TV, and now houses the headquarters of Reddit.)

During World War II, KPO's news bureau was the major source of NBC of news about the war in the Pacific, and operated shortwave radio stations (transmitters located in Dixon) serving the world. It was at the KPO (RCA) shortwave facility that the message was received that Japanese emperor Hirohito had surrendered, ending World War II.

On November 12, 1947, the Federal Communications Commission (FCC) approved NBC's application to change the call sign from KPO to KNBC, to strengthen its identity as an NBC station (and the only radio station NBC ever owned on the West Coast). This change lasted until 1962, when the network moved the call sign to its television station in Los Angeles, and the radio station was renamed KNBR.

In November 1949, NBC television affiliate KRON-TV went on the air. Only before the TV station's first airdate did NBC fight for the construction permit for the TV station until it lost the bid to the de Young family, then the owners of the San Francisco Chronicle.

In the 1950s when NBC scrapped its comedy, drama, variety shows, and serials, the Los Angeles facility was sold and demolished, and KNBC/KNBR once again became the West Coast NBC network control center and West Coast NBC Radio news operation.

KNBR evolved into a Middle of the road music format mixing in Adult Standards with Soft Rock cuts by the early 1960s. The station continued to be a news intensive format with personalities in the foreground and music in the background. Personalities included Frank Dill, Les Williams, Dave Niles, and Jack Hayes. Until January, 1975, KNBR carried NBC's long-running weekend show, Monitor. By the mid-1970s, KNBR evolved musically into a straight ahead adult contemporary music format and continued as such into the 1980s.

In 1989 NBC sold KNBR to Susquehanna Radio Corporation. It was the last radio property held by NBC, which two years earlier made the decision to sell off its radio division following General Electric's 1986 acquisition of RCA. The station soon added some sports talk in evenings, and took a full-time sports format in 1990 with the lone exception of The Rush Limbaugh Show, which KNBR carried from 1988 until 2000.

KNBR carried programs from ESPN Radio and KTCT aired shows from both ESPN Radio and Fox Sports Radio until 2013, when both stations switched to the Cumulus-distributed CBS Sports Radio.

In 2015, KNBR's studios were relocated from 55 Hawthorne Street to 750 Battery Street after parent Cumulus Media consolidated its San Francisco radio stations in one building." (visit link)
