"When Twin Peaks debuted, it got thirty-three share in the last half hour. That's in a pre-cable universe, but it was still unbelievable. It was as if the earth shifted in the television business for a minute and the notion of doing something quirky and different and odd and weird became something that could be possible in TV. 'Quirky' never was something that existed in TV before that and that's what David and Mark did with Twin Peaks and it was a … shocker."

Twin Peaks' mood, odd humor, and intimacy seduced a lot of people. There was definitely a shift in the collective subconscious after the show aired.
