I could have sworn I had asked this before but can't seem to find it, so I'll ask again. Is there any particular reason why the BBC have the home page for News, Sport etc set to a wider resolution, then when you click on an individual story the screen gets narrower? I wonder if this is something they'll address/fix when Reith gets rolled out site wide?
The news homepage was redesigned a while ago to show more content with more pictures. The project only covered the homepage and as part of this the news homepage was also moved to the cloud (the rest is on their own servers, which don't scale to demand).
The BBC News site is huge and making changes isn't easy - at the moment they're having to do a lot of work on getting ready for HTTPS.
Using a wider page for everything else just isn't a desperate priority for them. It is slowly being rolled out (for example with local news pages), but there's also the fact that for end users, a very wide screen leads to very long lines of text, which for many people can be hard to read.
Changes might come with Reith, but BBC News online don't generally do changes with a big bang, they're gradual.
Finally the market data section on the BBC News site has moved into the new layout, though in terms of appearance has taken a step backwards in my opinion http://www.bbc.co.uk/news/business/market-data.
In another change I've just noticed /bitesize (and /education) now redirects to https://www.bbc.com/education/beta. Interesting to note it takes you to bbc.com, rather than '.co.uk.'.
On some Connected TV platforms the previous standard
Colour Depth 24 bits per pixel and Screen and Layout parameter of 1280*720 pixels has been replaced with an upgraded
CD of 32 bpp and the Screen parameter is now 1920*1080 pixels.
