Missing/Unknown PRES of Televison

I have been planning to do this thread for a while but its keeps getting put back for unknown reason.

It's A new year and it's a new start in trying to improve pres sites across the internet, while many dates now being sorted, this now leaves the next issues, Missing pres....

Part of the problem is many of us have no idea what archive is missing, and since we dont know whats missing why would any one go looking for it, on the other side, someone might have a copy of something but not clicked its missing.

Its really does span BBC, Ch4, old ITV companies.

Can anyone think of any missing pres?

Can this be done somewhere else, such as in Requests or Media Websites?

why? Im not making a personnel request, nor is about media websites, since im asking about actually pres. Strange that on TV pres forum

You're requesting help and you stated the following.

There are known knowns; there are things we know we know.
We also know there are known unknowns; that is to say, we know there are some things we do not know.
But there are also unknown unknowns – the ones we don’t know we don’t know

Someone been watching Who Wants To Be A Millionaire,,,,

Or maybe they're quoting the person the person on Millionaire was?

Lets get started as to what I mean:

* Scotland today 1989 - 1990 ( I have only known about this since yesterday)
* Night School --- BBC 2 A Lot of people have no idea of this service back in the early 90s;
* C4 specials ident, I have no idea what is missing in this section.

Does anyone know of something which they think is missing?

I'll make that a known known by asking what has Millionaire got to do with it?

Some bloke who won a million quid, bought it up. It was repeated on Challenge a few weeks ago.

This is the original source of the quote, of course:
