Local owners signed on KLOR-TV, Channel 12, from Portland, Ore.,
in 1955 as an ABC affiliate with a secondary DuMont affiliation. On
the following year, KGW-TV, Channel 8, signed on the air and took
the ABC affiliation from KLOR-TV. The DuMont Television Network
went out of business, leaving KLOR without a network affiliation. 

George Haggerty purchased KLOR-TV in 1957, along with rival
KPTV.  KPTV launched in 1952 as the state’s first TV station.  It
was an NBC affiliate and the nation’s first commercial UHF TV
station, broadcasting on Channel 27.  (FADED SIGNALS)
