Z Film Custody After Zapruder went home-AUDIO ONLY-Thompson, Groden Bootlegs-Copyrights-JFKES e4, e5

No slides here of any kind, just audio. From Jeff Crudele's excellent, but IMO overly-sympathetic with impossible explanations from the gov't, podcast "JFK Enduring Secret."
There's a fifth episode, that I listened to and it's interesting but doesn't really bear on what I'm looking for, which is, the custody of the film before it was altered. This is about the copyright battle, or lack thereof, with ABC, Groden, and LIFE (whose exec's passed out copies to their friends, which were then bootlegged. Crudele speculates this was where the films show to college kids came from:

Zapruder mysteriously did not sue any of them. IMO he knew where to film from because he knew what was planned. He was rich from the film and other ventures and so were his children. They could have sued ABC and LIFE. LIFE could have and was contractually obligated to sue ABC (after they aired Groden's bootleg) but they didn't & only pretended to consider it. Zapruder, if this was all about the money as per the narrative, could have gotten substantially richer although it would have been a drawn out expensive lawsuit if he or his descendants took on ABC or LIFE, who split the proceeds of the film more-or-less down the middle with Zapruder. The TV stations never sued each other, either bc of the potential cost or mutual agreement in the industry and/or the gov. I see the latter. Anyway it's an interesting episode & it's here:

Lots of devil's advocate arguments but they provide a good counterpount without going too far the other way. More realistic description of the custody record:
