Depends which category you believe is the main one. As most people still get their tv news from the traditional bulletin, I'd have thought the Ten won the "main" one.
The new graphics were on show at the internal News Festival last month, so I'd guess they can't be too far away.
So what did they look like? Will the presenters still be in vision? Will the old symbols remain?
The weather centre were there to give people the chance to have a go at presenting a forecast, so the presenters will still be in vision. Can't imagine that anyone would have thought otherwise, really.
As has been said before, there was a fly-ver effect, showing clouds and rain. The only traditional symbols actually on the map appeared to be the temperatures, in their familiar circles. There was also a screen listing lots of locations, with the symbols used to summarise the weather.
Of course, what they had on show may not be the final version. They may be tweaking the system before it goes live.
In certain areas, the main network newscasts are shown at 5:30... so you'd get a news sandwich in the early evening:
5:00 - local news
5:30 - national news
6:00 - local news
6:30 - regular programming
This is certainly what happened in Chicago. In fact the local ABC affiliate also had an hour long local news programme at 4pm (although the presenters changed at 5pm).
The time zones make things very strange across on the west coast, though. For example, the affiliates over there record the breakfast shows and play them out at the 'correct' time over there. And many awards ceremonies take place early in LA, so they can go out live on the east coast, but are broadcast recorded in LA itself!
South Today and BBC London occasionally share reports. An example I can remember was a story about commuters on the Brighton to London line, who refused to comply with the no smoking ban on the trains.
