Didn't the NC show WNA at one point when they were still at TVC? I do remember it was still being presented by Matt Frei, but iirc it was shown during the overnight period and edited down to 30 minutes.
WNA has moved around quite a bit in the schedules (and there were two US-originated bulletins at one point ISTR - one presented by Matt and one present by Philippa or Katty).
Originally WNA was created as a flagship evening news bulletin for BBC America (the BBC cable/satellite channel in the US) and the BBC Washington operation was beefed up significantly to partly produce it. The Editor of the show, Rome Hartman, had just moved away from editing Katie Couric's revamped CBS Evening News ISTR (that launch didn't go that well...). WNA was quite well regarded in the US - and offered a different view to the US network offerings, though was obviously far lower budget in studio terms, it was able to use the massive international news gathering operation the BBC has globally to deliver a much less US-centric offering. It was still produced via both a gallery in D.C and a gallery in London (so viewers in the US saw the output of Washington via the London gallery) but there was a pretty decent team in the US both technical and editorial.
ISTR that in this era the News Channel (it may even have still been News 24?) took the first 30 mins - but can't remember if that was a live 30 mins or a turnaround.
However WNA did sour relations with the existing PBS stations who used to take BBC World News for a number of bulletins, as they weren't allowed to carry WNA, and it effectively competed with the bulletins they did carry (which were a bit watered down in comparison)
BBC America decided to move in a different programming direction, and so the funding that allowed for the big show to continue was pulled. Matt Frei moved on and the relationships with PBS were mended. The transmission time for WNA also moved, as it was now decided to align it with the schedules of the PBS stations that take it, rather than BBC America's schedule. These days it is far more produced from London with a presenter sitting in a studio in D.C. and a small team there.
