KETC

Background
KETC is a PBS station affiliate located in St. Louis, Missouri and first aired in September 20, 1954.

1st ID (September 20, 1954-196?)
Visuals: There is an image of a filmreel turning over a background of stylized apartment buildings. A circle appears, which has holes in a diamond pattern (representing a filmreel, obviously) with "KETC" in each hole, arranged like this:

Serif

"CHANNEL 9 ST. LOUIS" is shown below.

Technique: The live-action filmreel, the fading in of the animated filmreel.

Audio: Just an announcer saying "Produced by KETC.".

Availability: Parts of it (and the other logos up to the 4th one) were seen on the station's 50th anniversary special, Because of You: 50 Years of Channel 9.

2nd Logo (196?-Late 1970s)
Visuals: Against either a black or a dark blue background, there is a black 9 inside a color wheel. Inside the 9 are a white dot, and a white half-face with a black dot. There's some text that reads "Serif", with two dots between "Serif" and "Serif" for one, and "Serif" and "Serif" for the other.

Variants:
 * This is either filmed or videotaped.
 * The words next to the logo depend on the type of material the show was captured on:
 * Filmed: "A KETC FILM PRESENTATION" in yellow, where the logo is filmed.
 * Videotaped: "A KETC VIDEOTAPE PRODUCTION" in white, where the logo is videotaped. Below is "Copyright (year) by KETC-TV".
 * Another version has a smaller logo in the center with a copyright below reading "(C)(year) by KETC-TV".

Technique: Just a still logo.

Audio: The closing theme of the show, and an announcer saying "This program was produced by KETC Television, St. Louis, Missouri.", or no announcer, or no closing theme.

Availability: Can be seen on shows like Letter People and Self Incorporated. The "FILM PRESENTATION" variant was featured on the station's 50th anniversary special, Because of You: 50 Years of Channel 9.

3rd Logo (1976-1980)
Visuals: Against a dark blue background, there are the letters "Serif" inside a segmented box, being formed from top to bottom, and flickering in different colors while it's sliding from the bottom right to the center of the screen. After some time, the logo flashes rainbow colors, and the background turns yellow, and the letters turn blue, following a bright flash on the screen. The call letters are sandwiched between "Serif" and "Serif" (the former being cerulean blue, and the latter being baby blue). Three stars then sparkle on the logo, and as it fades out, a light wipes from left to right on the logo.

Technique: Early CGI light effects, plus the background changing.

Audio: A calm, soothing Moog synthesizer jingle.

Availability: Appeared on channel programs from the era, such as Airtime. It also made an appearance on the station's 50th anniversary special. If PBS puts out a DVD of either one of these shows, you might be lucky to find this logo.

4th ID (1978?-1988)
Visuals: On a black background, the familiar "9" logo slides from left to right, leaving a trail, starting off black with a  outline, but then filling in  when it almost comes to a stop. The text "Times New Roman" fades in above the logo.

Variant: On local programming, the "9" animates as usual, zooms out, and new text appears, such as "WEEKDAYS", "TONIGHT", etc., while three stars sparkle on the screen.

Technique: Early CGI, again.

Audio: Same as the 3rd logo.

Availability: Seen only as a local bumper. It, like the first 3 logos, also appeared on the anniversary special.

5th ID (1988-1990s)
Visuals: On a CGI rendered skyline of St. Louis, there is a big "9" at the top of the screen. A line and "Times New Roman" slide in from opposite directions. "Times New Roman" fades in below "Times New Roman" and the skyline shines.

Technique: Simple CGI effects.

Audio: A quiet bell and horn theme with an announcer.

Availability: Only used as a station ID.
