20 years of the BBC News Channel (BBC News 24)

Jackie Rowley. Formerly of Sky and BBC. Last time I knew she was in charge of comms (or similar) for the Lib Dems but that goes back a few years.

Do you know where this screenshot originally comes from?

Someone who found out that her male co-presenter was getting paid more than her"?

Screenshot's quite interesting, as it's a 16:9 screenshot from a time when the channel was only available in 14:9, so must have been taken from the studio at the time or a master tape!

That shift was single-headed, so no co-presenter...

(After Jackie Rowley left the BBC I think she went to work for the late Charles Kennedy when he was Lib Dem leader)

That's why I was wondering where it came from. Very nice to have as it confirms that the clock background extended all the way to the edge (so my mock is correct!)

Given that the website it apparently came from includes a cv with "Launched BBC News 24"...

Weren’t a lot of hours branded as “x o’clock News” at one point?

Yes - single headed shifts in the evening had that branding. Except from memory there wasn't a 9 O'Clock News - no doubt the BBC One bulletin weren't happy about that title being used elsewhere...

Kate Garraway (aka 'The Jennifer Aniston of News 24') and Matthew Amroliwala were the main presenters in that slot (not together)

No, just ten o'clock in the days of BBC News XXIV.
