Prism Leisure Corporation

Background
Prism Leisure Corporation was a British distribution company that focused on music, DVDs, VHS tapes, and even video and board games. Formed in 1980, the company went into administration in 2007 and was sold to FremantleMedia in 2010.

1st Logo (Late 1980s-1992?)
Visuals: We fade on to a textured cel-shaded floor. Then, a white triangle slides in as the camera shifts from an overhead view to a standing view, as yellow, (or yellow; it's really hard to tell with the poor quality),  and  trapezoids fly one-by-one each next to the triangle, forming a prism. The logo sits for a view moments before the text "PRISM LEISURE VIDEO", surrounded by a thin rectangular outline, stacked and flashing colors, spins onto the screen.

Technique: Cel-shaded CGI and Scanimate.

Audio: A trumpet fanfare combined with humming synths, which may be taken from a stock music library.

Availability: Seen on Prism Leisure tapes from the time, such as Spellbound.

2nd Logo (1992?-1997)
Visuals: On a black background, we start with a rather off-round sphere, which dissolves one by one to reveal a yellow rectangle. The rectangle gives way to form the word "PRISM", then "LEISURE" and "VIDEO" in white fade in afterwards.

Technique: CGI.

Audio: None.

Availability: Seen on Prism Leisure tapes from the time, such as Leprechaun.

3rd Logo (1997-2000)
Visuals: On a black background, a crystal "I" spins around as it flashes the colors of the rainbow. Then, "PR" and "SM", also crystallized, slide in next to "I", forming the word "PRISM". The word "LEISURE" fades in underneath in a different font.

Technique: CGI.

Audio: An ascending synth noise combined with sparkles, ending in a calm piano theme.

Availability: Appears on budget videos and DVDs like The Seductress.

4th Logo (2000-2002)
Visuals: On a space background, the then-new Prism Leisure logo zooms in towards the viewer.

Variant: For every "2 in 1" video release from the company, the logo plays as normal, then the logo brings forth a title card which reads "PRESENTS 2 GREAT MOVIES ON 1 FANTASTIC VIDEO". The logo also reuses part of the 1st logo, this time in its normal tone.

Technique: 2D computer animation.

Audio: Part of the 1st logo played in a higher tone.

Availability: Spotted on the UK release of Titanic: The Legend Goes On....

5th Logo (2002-2007)
Visuals: On a space background, an explosion that brings forth a spinning prism occurs. The letters of "PRISM" in shiny fly out one-by-one as "LEISURE", also curved and in, zooms out underneath "PRISM". A spark then draws a rainbow around the prism that is cut off by the text. The words "CORPORATION, PLC." shoot out at the bottom of the logo, and the prism stops spinning at this point, thus creating an updated version of the 4th logo.

Technique: CGI.

Audio: A droning synth is heard throughout the logo. A sustained explosion is heard at the prism's grand appearance, whooshes and whirs are heard as the words appear, and sparkling is heard as the rainbow is drawn.

Availability: Seen on DVD and VHS releases from the company during the time, such as Inspector Gadget, Madeline, Charlotte's Web (1973), Animalympics, My Little Pony: The Movie (1986), The Transformers: The Movie, and The Brave Little Toaster, among other titles.
 * FremantleMedia releases don't use this logo, they simply went with their logo.
