KBDI

Background
KBDI-TV (or Colorado Public Television) is a PBS affiliate serving Colorado.

ID (198?-1997)
Visuals: We see a CGI image of a skyline, with black cities. "KBDI", colored blue, scrolls up and tilts into place. "presents", in a cursive font, writes in.

Variant: A version exists where a still image without presents flips to change into a still image of the 1987 WTTW logo.

Technique: All CGI.

Audio: A small whoosh, followed by a five-note synth sounding like a Macintosh death chime. Later it was lower pitched. The variant has a guitar tune.

Availability: Seen on The 90's.
