The dates were as follows:

16 Oct 2000 - The Oxfordshire area broke away to join South Today, with its own sub-opt
4 Aug 2001 - Newsroom South East moved from Elstree to Marylebone High Street and began broadcasting in full widescreen
3 Sep 2001 - The Kent area broke away (with East Sussex breaking away from South Today) with the launch of South East Today. This left Newsroom South East broadcasting only to what would be the new London region
1 Oct 2001 - BBC London News launched, replacing Newsroom South East

First off learned fellow, thank you for your knowledge. Secondly, I didn't realise the following occurred:

1) That what would become the South Today (Oxford Opt) broke away so early in the process. Virtually a year from the end goal.
2) That NSE moved from Elstree to Marylebone High Street. I have always thought that it stayed in Elstree until the very end.
and
3) That come the clips of the end of NSE before the launch of BBC London News. It was in effect "BBC London News" anyway.

As I said. Thank you.
