Planet 24

Background
Planet 24 was a television production company initially founded as Planet Pictures by Bob Geldof and Tony Boland in 1992. They would soon merge with 24 Hour Productions, renaming the company to Planet 24. In March 1999, Carlton Communications acquired the company and would soon merge with Carlton Productions several years later.

1st Logo (28 September 1992-1996)
Logo: On a white background, the 3D gold letters "Times New Roman" flip in individually while a star flies above and turns around, aiming to orbit around "ET" in "PLANET" while a dark purple box fades in. The star then stops underneath the number "2", creating a ring shape. Additional credits may appear below.

Variant: On Delicious, the logo appears within the 1995 Carlton UK Productions logo.

Technique: The letters flipping in, the star moving, and the box fading in.

Music/Sounds: Two descending chimes when the star orbits around "ET". Otherwise, none or the ending theme of the programme.

Availability: Rare.
 * Seen on series 3-5 of The Word, early episodes of The Big Breakfast, and Surf Potatoes.
 * Archival sites such as Screenocean has this logo intact.

2nd Logo (1996-29 September 2004)
Logo: On a still sunburst background, with a very dark purple box in the center, several lens flare rapidly fly in and form the text from before from right to left, showing them with more shine. They have also left smoke floating within the box. After all of this, a star flies in from the left and proceeds to orbit around the section "ET 2", creating a  ring and then stopping in between the two words.

Variants:
 * A copyright stamp may appear underneath the logo. Sometimes, it includes the Channel 4 name.
 * On The Big Breakfast, the copyright notice is purple and lower.
 * On Gaytime TV, this logo shares the screen with the 1988 BBC logo.
 * Like many other co-produced Channel 4 variants in the early 2000's, this logo appears on the left side of the screen with its background intact and said network's logo on the right.
 * On Can You Pull..., the logo is wider and shorter and the background is white.

Technique: The sparks forming the text and the star flying.

Music/Sounds: Several reverbed whooshes when the text appears, followed by a sleeker rendition of the two chimes from before. Otherwise, none or the ending theme of the programme.

Availability: Can be seen on later episodes of The Big Breakfast, Best Of The Word, Watercolour Challenge, and the company's last series, Can You Pull....
