Dennis Potter’s Blackeyes: four part mini-series that was broadcast by the BBC in 1989 and keeping in tradition with Potter’s work, elicited widespread controversy because of the sexual content. I haven’t seen it repeated anywhere since the original airing and it’s commercially unavailable on any home video format - which is strange because nearly everything else that he wrote and produced for various TV networks during his lengthy career has been released on DVD.

Midnight Patrol: Adventures in the Dream Zone aka Potsworth and the Midnight Patrol - also broadcast by the BBC under the title of Potsworth & Co. 1990 Hanna-Barbera production which featured the original TESB Emperor, Clive Revill in the lead voice role. Enjoyed massive ratings in the US and UK during the original run but no further seasons were commissioned. Apparently Hanna-Barbera Video marketed a compilation of several episodes on NTSC VHS but there has never been a complete release on any home video medium.

Another Gore Vidal entry… His excellent 1996 “American Presidency” mini-series is only available on VHS and even that is hard to find and commands ridiculous prices. Someone has uploaded a copy to YouTube but imho it deserves to be savoured in high quality.

Canadian TV news drama, E.N.G. - ran for five seasons, was broadcast internationally and received dozens of awards and nominations but nonetheless the production company, Alliance, has no plans for a DVD release.

Midnight Caller - three season Talk Radio drama, produced by Lorimar and broadcast on NBC and in the UK on the ITV network. A winner of two primetime Emmmy’s and several other nominations because the story lines never shied away from controversial subject matter. Hasn’t been issued on DVD and I don’t think there was even a VHS release.
