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.
