It was pretty much the Millennium that highlighted how crap London fireworks were on NYE and I think still a few years before they became the more familiar display - possibly 2005 to tie in with the Olympic bid.
2004/05 was the first year we had the fireworks broadcast live on the Beeb, which we've had ever since. As mentioned, though we had them for the Millennium, we didn't have them after that for a few years. In 2000/01, there was a special lottery show with live reports from across the UK, and in London it was Bradley Walsh with about a dozen people and pretty much nothing happening.
Now the fireworks are so established everyone forgets that before that there were all kinds of things at midnight. Clive James was the longest running fixture for seven years but before and after that there would be all kinds of things, sometimes a simulcast of BBC Scotland, Wogan, 'stEnders (in 1987/88 ), all sorts of stuff.
The worst ever show was this in 2001/02 -
https://genome.ch.bbc.co.uk/schedules/bbcone/london/2001-12-31#at-23.15 An atmosphere-free, blatantly pre-recorded affair with a host of BBC standby guests and Vic and Bob, who I dearly love, doing the thing they always do on these shows, coming on with no material and dying on their arse. At five to midnight we had Vinnie Jones plugging his latest film, it was such a boring show.
Did anyone spot an ancient repeat of Angus Deayton's Before The Were Famous last night on BBC2? I think I was a bit too young when this show was first on as I was completely unaware that this was a studio-based show with an audience and an on location pre-titles sketch that added nothing to the show - two things you'd never get on an equivalent version of the show today. They constantly had the audience laughing over clips that weren't funny, seemingly to justify having the audience there.
Well, I would take issue with them adding nothing to the show, because Before They Were Famous was a brilliant show in its day (the first one in 1997 pulled in one of the biggest audiences of the year and literally everyone was talking about it), and just as important as the clips was Angus, beautifully delivering a script written by himself and Danny Baker, which like Denis Norden on Alright on the Night illustrated that it wasn't just flinging a load of clips together.
