Soul Purpose Productions

1st Logo (December 25, 1991-September 17, 1995)
Visuals: Over a black background, there's the stacked white text "Times New Roman PURPOSE PRODUCTIONS". The "O" in "SOUL" resembles a stylized camera shutter, the "S" in said word is larger than the rest of the letters, and the last two words are divided by a thin bar. Underneath, there are additional in-credit notices indicating a production for a particular channel.

Technique: A still, computerized graphic.

Audio: The ending theme of the programme.

Availability: So far, it appeared on Pharaohs and Kings: A Biblical Quest. An airing on UK Horizons also has this logo intact.
