Does anyone know the research that led Newshub, on TV3, to feature backgrounds that move or are animated, in some way? They are generally fixed images that slowly change position behind the presenter (e.g. the weather maps, but also on most backgrounds) though the sports section features a bit more with constantly changing bits of images, not necessarily even relevant to what is being presented.

I suppose it's trivial but it can be distracting and I can't think of a single possible reason why the producers thought it was a good idea.

Oddly, on one programme (I think it was The Nation) only one camera featured the movement, another camera position showed no movement with the same background. It's bizarre.

Thoughts?
