If I have my facts correct, the Frankenstein version of "The Cage" was shown on television for the first time
No, the b/w & color compile was a direct-to-video release. Then
the lost color negatives were found. Then
the all-color restored version was aired on TV, as part of "From One Saga To the Next", to kick off Season 2 of TNG, and then was released on VHS.
