[Newsroom]

Smart glass is one of those things that seems like a great idea for a news set, until you actually have to use it - particularly as having projectors 'open' and competing with studio lights is only going to create a weak picture at the best of times. They were going to use it again in Studios C and E when they moved to NBH, but luckily realised it didn't work in the piloting stages and replaced them.

In fact, you can actually still see them (and their much weaker image) in The World's Newsroom trailers.

Gosh I absolutely loved those promos and the soundtrack used. Such a brilliant choice of music.
