This is a bit of a weird one but this bloke runs a site similar to Wikileaks and was invited for interviews at the New York bureaus of the BBC and Russia Today. For whatever reason he decided to tape literally everything while he was in there giving an interesting look inside their newsrooms.
Interesting that the 1997 CBBC idents were in widescreen, I always thought that the sped up/zoomed in ones used from late-2001 to 2002 were introduced because the previous idents were made in 4:3 and CBBC went widescreen at the same time.
