[Neil Jones]

I'ld rather see an announcement of some of the older shows people remember getting some sort of streaming release (Home media would be nice too but suspect that ship has sailed)

It's not so bad for much of the aquired content, but shows like Splatz, Mike and Angelo & the Rottentrolls stuck with circulating the tapes.

Some of it is available, albeit it not all of it.  T-Bag is on DVD, in some form at least.  Roger and The Rottentrolls was released in 2020 in DVD:
www.amazon.co.uk 

The rest of the shows is probably due to lack of demand and/or rights issues.

The ship has not sailed for home media, by any stretch of the imagination.  People said the ship has sailed for vinyl and cassette - the former has made a return and the latter is probably not far away.
