Radio KPOJ-AM (Portland's Progressive Talk)

KPOJ (620 AM) is a radio station located in the Portland, Oregon, area. It airs a progressive talk format and was an original Air America Radio affiliate.

For more than 70 years, the station at AM 620 was KGW, founded in 1922 by The Oregonian newspaper and owned and operated by it until 1953, when it was sold to King Broadcasting. KGW affiliated with the NBC network in 1927 and stayed for 29 years until joining ABC Radio in 1956.

Among KGW's early personalities was Mel Blanc, a local musician and vocalist featured on the "Hoot Owls" variety program from 1927 to 1933. Here Blanc discovered a talent for character voices that would win him stardom as the voice of Bugs Bunny, Daffy Duck and many other Warner Brothers cartoon features.

Under The Oregonian the station gained an AM sister, KEX, in 1933, and the Northwest's first FM station, KGW-FM (now KKRZ), in 1946. King Broadcasting founded KGW-TV in 1956. All three stations continue to exist in Portland, but none have any remaining connection to AM 620.

"62 KGW", as it called itself during its later years under those call letters, was one of the most popular radio stations in Portland in the 1960s and 1970s, but its ratings declined during the 1980s, and on August 28, 1989 the station changed from a Top 40 music format to a talk format, using primarily local hosts. The change did not produce the hoped-for ratings turnaround, and in July 1991 the talk programming was replaced by a simulcast of sister station KINK-FM's programming, but retaining the longstanding and locally well-known call sign, KGW, until 1993, when the call letters were changed to KINK. In 1995, KINK-AM changed back to all-talk, now airing nationally syndicated talk radio programming instead of local talk, and the call letters changed to KOTK. The frequent changing of call letters continued, with the station becoming KEWS in 1997, KDBZ in 2000, and KTLK in 2002. The station picked up the current KPOJ call letters on August 18, 2003. For many years and with various formats, the station called itself "Super 62".

The KPOJ call sign originated at what is now KKPZ AM 1330, which for many years was the Mutual Broadcasting System's Portland affiliate. In the 1970s, that station changed its call letters to KUPL. The call letters stand for Portland Oregon Journal, the now-defunct newspaper that once owned AM 1330.
