WTVS

Not to be confused with the ITV owned affiliate TVS.

Background
WTVS is a PBS affiliate located in Detroit, Michigan that also serves Windsor, Ontario.

1st Logo (1978-1986)
Visuals: The camera flies over a live-action shot of downtown Detroit as the text "From WTVS/Detroit" zooms away slowly.

Technique: Live-action footage with chyron effects.

Audio: A warbling shuttle sound with an ascending whoosh and whistling sounds.

Availability: Seen on pre-1992 VHS prints of David Macaulay's Castle. On the 1995 PBS Video (and later PBS Home Video) release, this is plastered by the WHYY-TV logo, which is then moved to the end.

2nd Logo (1986-1991)
Visuals: Against a purple/tan background, an abstract, light purple multi-lined "56" arranges itself on a dark purple square as it zooms out to the top left. Then, the background fades to a skyline of Detroit, and the text "WTVS/Detroit" slides out from the bottom left of the screen.

Technique: Analog computer animation.

Audio: A rising synth chord followed by a rather spacey three-note tune.

Availability: Only used as a local ID.

3rd Logo (1986-1991)
Visuals: The screen fades into a close-up shot of the Milky Way before zooming away, passing by the Earth, then arrives at the Detroit skylines. As soon as the zooming stops, the words " THE UNIVERSE ", " THE WORLD ", and " DETROIT " all zoom out stacking on each other, and then the text "and you" is written in in cursive, and the WTVS logo of the time fades in below.

Variants:
 * A production variant exists, where the background is seen without any text. "FROM" and "WTVS/DETROIT" slide in from the left and right respectively, and fold down to straighten out.
 * There is a shorter version that just starts at the texts zooming out.

Technique: Analog computer animation.

Audio: A majestic eight-note synthesized orchestra tune, with a "ding" at the beginning. The shorter version uses a quicker, 10-note synth tune, and the production variant has a shorter version of this.

Availability: Seen with the "Skyline" ID, this was used as a "You're watching..." ID on WTVS. It would then cut to a national program intro tag at the time.

4th Logo (1991-1998)
Visuals: On an animated blurry background of different shapes (like the 1998 logo), there is a spinning Taijitu (used in representing yin and yang, but lacking the dots) with one half and the other pink. "Impact" in a white Impact-like font fades in above. A sphere (kind of like the Moon) with "Impact" in the same font on it zooms in. "Impact" in the same font and in white fades in below.

Variation: There is a version of this logo without the "Impact" header, which was commonly used as a local funding bumper from 1993 to 1994.

Technique: Camera-controlled animation.

Audio: A 4-note orchestral fanfare, or silent with a voiceover for the local funding bumper from 1993 to 1994.

Availability: Only known to appear on Club Connect.

5th Logo (1991-1998)
Visuals: The camera pans through a hallway with a bunch of PBS program clips on the walls. When it reaches the exit, the hallway is revealed to be a circle that rotates, revealing the "56" logo. The logo shines as "Impact" fades in below it, then fades into "Impact".

Variants:
 * Sometimes this logo is abridged, starting as the circle rotates, and "Impact" is omitted.
 * On signoffs, a still version of the finished ident is used.

Technique: CGI produced by Sage-3D.

Audio: A mild action news-like fanfare which then turns into harp music and the four notes from the previous logo on a flute followed by a bassoon. On the abridged variant, an announcer says "You're watching WTVS, Channel 56 in Detroit."

Availability: Only used as a local ID.
