A small group of British Television enthusiasts, Kaleidoscope, did much to promote the programme and negotiated the rights to rescreen, at conventions and meetings, many of the black-and-white Thames episodes and the remaining ABC episodes. They also unearthed a 1968 ABC promotional reel, on a long-obsolete domestic videotape format, which included a five-minute extract from the otherwise-missing third series episode "Must Be the Architecture, Can't Be the Climate" and audio recordings of several lost ABC episodes. Most notably, Kaleidoscope organised and hosted a 'Public Eye: Thirtieth Anniversary' convention in 1995. This was attended by Alfred Burke in person.
