When did cable tv come out in Seattle wa?

Apparently to me it did not come out till 1989 there was no tv before just old tubes supposedly black and white but i figure it was reversed engineered as a scam and the tv came with about 15 buttons and later a dial knob where you turn it to change the channel. First there was no t.v. then a t.v. with buttons then a turn channel changer and then a Nintendo. I think they might be lying for sure about where this stuff comes from when it was made etc..,
