Keystone Entertainment
Background
Keystone Entertainment is the production company of Robert Vince, the creator of the Air Bud series of films. A company based in the United States related to Keystone - Air Bud Entertainment holds the rights to the company's works.
Logo (1995-)

Visuals: Over a black background, the 3D steel word "KEYSTONE" zooms out to the screen and shines. Then the spaced-out word "E N T E R T A I N M E N T" (set in Arial) floats from below. The "T" letter expands its head to fit the whole logo width.
Variants:
- Sometimes, a prototype version of the logo exists. The animation is slower, the logo is now more steelish (but more realistic than ever), and "ENTERTAINMENT" is in an Avant Garde Gothic font.
- A still version of this logo exists at the end of Air Bud.
Technique: CGI.
Audio: A soft orchestral tune.
Audio Variant: On the prototype variant, a brief gust of wind plays, and a crystallized shimmering sound is heard, followed by a noisy drone as "ENTERTAINMENT" lifts upward. Also, a synth choir (played in D major) is heard at the end.
Availability: It was seen on White Tiger, Air Bud and its numerous dog-themed sequels and offsprings.
