The RCA distribution deal in place, here's a late summer 1983 catalog for LDs released by RCA/Columbia Pictures Home Video.
The Currently Available page illustrates the launch group for Columbia on LD with a few additions. Only title missing is
"The Blue Lagoon," which did see an early LD release and disappeared for a few years until returning on the RCA/Columbia label.
RCA became involved in distributing Columbia Pictures in effort to supply product for the CED videodisc system.
