Barbour/Langley Productions

Background
Barbour/Langley Productions was established in 1983 by Malcolm Barbour and John Langley, the creators of Cops. It didn't use a logo until 1988. In 1994, Barbour left the company, and two years later, the company was renamed to Langley Productions to reference the departure, though the previous name was still used on Cops until 1999.

1st Logo (November 2, 1988-December 12, 1992)
Visuals: Over a black background, the text "BARBOUR" flies from the right of the screen, with "LANGLEY" doing the same thing from the left. They both criss-cross and land on opposite sides, and a white slash draws itself between them. "PRODUCTIONS, INC." appears below. The end result is this:

BARBOUR/LANGLEY PRODUCTIONS, INC.

Variants:
 * On season 1 of Cops, a copyright notice would appear.
 * An early version of the logo exists where the logo disappears with a television switch-off effect.

Technique: Computer animation.

Audio: A dramatic 8-note synth tune that begins with 4 descending notes, followed by a 5th done on synth strings when the words land. Then 3 more ascending notes follow. This was all done on a Roland D-50 synthesizer with the patches "Future Pad" (for the descending and ascending notes) and "Pizzagogo" (for the 5th note).

Availability:
 * It can be seen on 1989-1992 episodes of Cops.
 * It was also seen on very early episodes of Code 3 and American Expose: Who Murdered JFK, respectively.

2nd Logo (August 15, 1992-September 18, 1999)
Visuals: Almost the same as before, except everything is and in 3D, and occurs at a faster rate. Also, there is no "INC." at the end, and the text is in Univers font.

Variant: Some episodes of Cops in the logo's first year have the "BARBOUR/LANGLEY" text shining.

Technique: CGI.

Audio:
 * 1992-1993: The last logo's theme, which was sometimes shortened.
 * 1993-1999: A southern guitar riff.

Audio Variant: Some Cops tapes have a silent variant.

Availability:
 * It appears on 1992-1999 episodes of Cops.
 * A still version of the logo may appear on Spike airings on Cops.
 * It was also seen on later episodes of Code 3.
