I have looked everywhere on YouTube and I can't seem to find Thames television's last program. I don't know whether this can be found in the itv archives but i am not an employee. Would anyone have an old recording that could be digitized so that i may watch it? Please?
Technically speaking the last "programme" that went out on Thames was the news in the lead up to midnight:
(back in the days before it became all about who could put on the best firework display)
Prior to that was Richard Dunn's announcement and what you can see the final endcap of was the previous programme, "The End of the Year Show The Best...From Thames".
That wouldn't be with ITV anyway, it'll be with Fremantle, like the rest of the Thames back catalogue. It was probably just a retro lookback.
For completeness, here's one of the two videos of what was going on behind the scenes at Thames on 31 December 1992:
(the other one covers up to midnight and the handover to Carlton)
