History


650 KPCB (1927 to 1937)

The station began broadcasting on April 27, 1927, as KPCB on 650 kilocycles. Its founder was Moritz Thomsen of the Pacific Coast Biscuit Company (hence the

KPCB) and it was powered at 100 watts. Among its announcers was Chet Huntley, later of television's Huntley-Brinkley Report. In 1935, Saul Haas's Queen City Broadcasting Company took over the station. Queen City increased the power to 500 watts. Haas, who was well connected in liberal politics and the business community, wanted a simple, pronounceable, and recognizable call sign for his new station. He chose KIRO, which is usually pronounced like the capital of

710 KIRO (1937 to 1960)

In 1937, KIRO was assigned the AM 710 frequency and was granted an increase in power to 1,000 watts. Soon after, KIRO acquired the Seattle CBS Radio Network affiliation rights from KOL. Known as "The Friendly Station," KIRO personalities broke from the formal announcing style that was commonplace during the early days of radio. KIRO carried CBS's dramas, comedies, news, sports, soap operas, game shows and

It initially simulcast its AM sister's programming but in the 1960s it became a beautiful music outlet. In 1975, it changed its call letters to KSEA and today is KKWF. Preparing for a future television allocation, KIRO moved in 1952 from downtown studios to a larger building on Queen Anne Hill. This peak was already home to the KING-TV transmitter and would soon be the site for KOMO-TV as well. Queen City Broadcasting was awarded Seattle's last remaining VHF TV license in 1958, and signed on as CBS affiliate

, in 1963. He earned a handsome return on his investment 28 years earlier. When the LDS Church reorganized its broadcasting properties as Bonneville International Corporation, Haas joined Bonneville's board. Bonneville executives Lloyd Cooney and Ken Hatch arrived in Seattle to lead KIRO-AM-FM-TV, in 1964. Like many network radio affiliates following the demise of full-time block programming, KIRO spent the 1960s playing middle of the road music in addition to long-form news and interview shows. Morning host Jim French spent several years broadcasting from the rotating restaurant atop the Space Needle and was live on the air from that perch during a 6.7-magnitude earthquake in April 1965. Bonneville moved its Seattle radio and TV stations to the newly constructed "Broadcast House" at Third and Broad Streets in 1968. In 1973, KIRO ended a 35-year affiliation with CBS and switched to the

radio station by the mid 1970s, playing music during the day, talk in the evenings, and more music intensive on weekends with exception of times when sporting events were broadcast. By 1980, the station played music during the day with talk heard night and overnights. The station added talk middays during the week in 1985. By then amounts of music during drive times were down to about 4 songs an hour and during the day, with weekends playing 12 songs an hour. In 1986, KIRO was reclassified as a news and talk station, adding more news programming and dropping music altogether. In 1993, Bonneville attempted to merge the staff of KIRO radio with that of then-sister station KIRO-TV in an attempt at synergy (the staffs merged in June 1992, with KIRO radio's general manager and news director Andy Ludlum at the helm). Dubbed the "KIRO News Network", this meant that KIRO-TV anchors and reporters would be heard on the radio, while KIRO radio personalities would be seen during KIRO-TV newscasts; during this period, KIRO's radio programming originated from a massive newsroom especially constructed for what was called "News Outside the Box", sharing space with their TV co-workers.

Sports broadcasts

Sports play-by-play has been a staple of the KIRO schedule throughout its history. Since the team's inception in 1976, KIRO has been the flagship radio station for the NFL Seattle Seahawks. About that same time, it was also the flagship station for the Seattle Sounders of the North American Soccer League. From 1985 to 2002, and again since 2009, the station airs

KIRO was also the radio home to popular sportscaster Wayne Cody, who did live sideline reports during Seattle Seahawks football games, Washington Huskies college football play-by-play, NASL Seattle Sounders pro soccer play-by-play, and hosted a sports radio talk show weeknights that was the only one of its kind at the time in Seattle. In January 2020, KIRO announced it would serve as the flagship station for the Seattle Dragons of the XFL; the wording of the press release made it ambiguous as to whether or not they would carry live games.


Dave Ross

Dave Ross joined KIRO as a reporter from

Ross unsuccessfully ran for Washington's eighth Congressional district as a Democratic candidate in 2004. While Ross unofficially announced his candidacy in May, he did not leave his on-air position until just prior to the July filing deadline. In response to complaints from state Republican party officials, Ross claimed that he was contractually bound to continue working for KIRO until he formally filed to become a candidate. Ross returned to the air immediately following the November election. He was moved to the afternoon drive-time shift in February 2005. Ross moved back to his 9am-noon shift in May 2006. Since January 2012, Ross has hosted Seattle's Morning News from 5-9 a.m. In addition to his KIRO work, Ross does a daily commentary on the CBS Radio Network and is also substituted for Charles Osgood on CBS Radio's "Osgood File" segments. After selling KIRO-TV to the A.H. Belo Corp. in 1995, Bonneville's Seattle radio stations moved to facilities on Eastlake Avenue. KIRO (AM), KIRO-FM (now KKWF) and KNWX (now KTTH) were sold to Entercom Communications of

Talk on FM, sports on AM
