There's been a slow decline terms of the way they present the news over the years. After John Craven, with people like Juliet Morris & Krishnan Guru-Murphy, it seemed to be a very serious news programme, just with the emphasis of simplifying the stories for the younger audience. This imo continued through Julie Etchingham, Chris Rogers, Kate Gerbeau (nee Sanderson), and Lizo Mzimba (when not reviewing Harry Potter), then started to shift somehow with Becky Jago & Ellie Crisell, and has continued to present day, where they don't seem to be that serious at all.
Maybe it's the problem as we grow ever older, and a use of rose tinted glasses, or maybe its just how society has progressed.
Don't forget that they changed the official target audience for CBBC and hence Newsround to be considerably younger a few years ago, so you can't really do a direct comparison.
I haven't seen NR for a while, but have they fixed the keying/matting on the screens? Last few times I've caught it there was a nasty jagged outline around inserts.
Write that down in your copybook now.
