Clearvue

Background
Clearvue was an educational company formed around either the 80's or the 90's to distributed educational videos to young children. One of their video series was the Fun to Learn video series, also known as Laugh and Learn, distributed by UAV Entertainment (later Sterling Entertainment Group). Clearvue was later merged with EAV to form "Clearvue/eav" and again with SVE to form "Clearvue & SVE" before recently being folded into Discovery Education.

1st Logo (Opening Logo) (1990-1992?)
Logo: On a black background, we see the word "Clearvue" in the Brandish font zooming in and spinning around. It starts out in rainbow colors but then turns a yellow color as it stops spinning. The slogan "Educational Enrichment For All Grade Levels" fades in below in blue.

Technique: The spinning and the color changing.

Music/Sounds: None.

Availability: Rare. Seen on the Fun to Learn video series. This does not appear on the Sterling releases.

2nd Logo (Closing Logo) (1990-1991)
Logo: On a blue background, we see the words "A Clearvue Production" in yellow, wiping in from the center.

Variants:
 * On the episodes "Learning About Responsibility and Sharing" (shown on the Laugh and Learn: Time VHS) and "Survival Safety Signs" (shown on the Laugh and Learn: Shapes VHS), the text is in three lines instead of two. The text also scrolls upward along with the credits rather than wiping.
 * On the episodes, "One, Two and Three", "Four, Five and Six", "Seven, Eight and Nine" and "Ten" (all shown on the Laugh and Learn: 123s VHS), the text is displayed in a fat font displayed on a green sign which Professor Centi (the main character on the aforementioned episodes) holds up. It is revealed via a rain-like wipe effect.
 * On the episodes "Falling Star and the Clever Clowns", "Shapelessville Shapes Up" and "The Circular Circus On Parade" (all shown on the Laugh and Learn: Shapes VHS), the text is in a different font, is in all caps and takes place against a blue square with a white outline, all presented against a maroon/peach psychedelic background. The text also scrolls up along with the credits and zooms out at the end.

Technique: The text wiping in.

Music/Sounds: None.

Availability: Rare. Seen at the end of the Fun to Learn video series.
