Davidson & Associates

Background
Davidson & Associates (or simply Davidson) was an educational software company headquartered in Torrance, California. It was merged with Knowledge Adventure in 1999.

1st Logo (Early 1990s?-1999?)
Logo: On a black background, a scribble is drawn in. "Davidson" is written first in a childish font, in which it then morphs into "Davidson" and the scribble morphs into a "D" shape.

FX/SFX: The logo drawing and morphing.

Music/Sounds: Sketching sounds followed by a cheesy synth orchestra.

Availability: Rare. Generally seen on Davidson's product previews which were bundled with their games.

2nd Logo (Mid 1990s?-1999?)
Logo: On a white background, all the letters of "Davidson" walk and bounce in from the right side of the screen, all scattered in a crowd. Then, the "D" shape from the previous logo slams down and sends all the letters flying, before they all fall down one-by-one in their normal positions.

FX/SFX: The letters and shapes moving.

Music/Sounds: A bunch of high-pitched chattering from the letters. A voice says "Yoo-hoo!", and there is a boing sound as the "D" falls down and a "Whee!" from all the letters as they fly away, followed by a synthesized tune as they re-appear, a "Ta-da!" and then them laughing.

Availability: Was seen on games such as Mega Math Blaster.

3rd Logo (1990's?)
Logo: On a dark blue background, a black or rectangle with the Simon & Schuster logo flies up spinning as a crooked  rectangle with the Davidson logo does the same thing. The rectangles then come towards the screen, soon going onto their own tracks and stop spinning, with the corner of the rectangle overlapping the black rectangle. The logo then flashes.

FX/SFX: The rectangles spinning.

Music/Sounds: A rising synth theme followed by a bang.

Availability: Very rare. This was seen on Simon & Schuster collaborations. Products with this include Chicka Chicka Boom Boom. A cleaner version appeared on a demo.
