70 years ago today, Palmer Lieberman’s KRSC-TV channel 5 took to the air. It’s first broadcast was a live football game between West Seattle & Wenatchee high schools on Thanksgiving Day 1948. At the time, it was estimated there were approx. 6,000 TV sets in the Sea-Tac area.
Shortly after it’s sign-on, it was acquired by visionary broadcaster Dorothy Bullitt, who would take the station to great heights as part of the King Broadcasting Co. empire.
As with many pioneer TV stations, very little actual programming was available & for hours on end, transmission of ‘test patterns’ would occupy broadcast time.
KING-5 has a story & some photos of the first broadcast on their local news web page.
