KOMO’s TV legacy started in 1929 when Francis Brott, an engineer at the radio station, broadcast televised images over electrical lines to small TV sets with one-inch screens.
The Fisher family signed on KOMO-TV in 1953 as an NBC affiliate. When NBC signed an affiliation deal with rival KING-TV in 1959, KOMO-TV became an ABC affiliate.
In 1984, KOMO became the first TV station to broadcast daily programming in full stereo. It also claims to be the first TV station in the United States to broadcast its daily newscasts in high definition, beginning in 1999.
