Celador

Background
Celador was a British television production company that was formed in 1981 by producer Paul Smith. Initially as an independent production company, Celador expanded to include several other subsidiaries - Celador Films, which produced feature-length films, Celador Radio, which owned several radio stations across the United Kingdom, Lusam Music, which handled music distribution for Celador shows, Celador Theatrical Productions, which handled theatre shows, and Celador International, which handled international sales of mainly game shows, while the production arm was renamed Calador Productions.

In 2006, Celador restructured its business and exited the TV industry. They sold Celador International to the Netherlands-based 2waytraffic in December 2006, while Celador Productions underwent a management buyout in 2007 and was renamed as CPL Productions in 2009. While the company retained its radio assets, it eventually sold it off to Bauer Media Group in 2019.

Currently, Celador Entertainment focuses its work on the theatrical and film markets.

1st Logo (January 9, 1984-1993)
Visuals: On a black background, the screen pans out the spinning letters that were connected together and flashes until it stops flashing. Then the pieces spread out in order to reveal the white-blue gradient words "celador" in a futuristic font. The words "a" fades in at the top left of the "celador" text while "production" is at the bottom right below the text. Below is a copyright disclaimer.

Variants:
 * A more common version of the animation starts where the letters spread out.
 * Sometimes, the logo freezes after "celador" finishes spreading then there is the white text "A Celador Production" and the station info is shown below like either BBC, Carlton Television or Thames.
 * A Christmas version of the logo exists. Here, the logo is shown on the bottom behind a sad snowman on a grey-white gradient background with snowflakes falling. Then the snowman turns happy and above it was "Christmas Entertainment for (BBC/Thames) Television from" and below it was a copyright stamp.
