This was a company of ITT Corporation, which produced the children's show The Big Blue Marble.
Visuals: After the preview for the next Big Blue Marble episode, we transition to a still space scene with a starry sky. In the upper right corner is the Earth, while on the lower left is "A PRODUCTION OF" in a gothic font. A tri-colored (red, blue, yellow) rainbow trails between the two, coming from upper left to lower right, with the name "THE BLUE MARBLE COMPANY" in ITC Avant Garde appearing inside of it in an arc formation. The font is plain except for the "M"'s and "A"'s being tilted, and the "T" and "H" of "THE" being "linked". The rainbow disappears leaving the name behind.
Technique: Cel animation.
Audio: A whimsical synthesized fanfare. The music actually begins as the "Next time" montage is ending.
Availability: Was seen on its namesake show, which has not rerun since 1983.
Legacy: This logo was considered one of the rarest logos on this wiki until its rediscovery in 2017 on an off-air recording.
