Looking for something entirely unrelated, I came across these two slides from July 2000. When I used these, they were printed on transparencies and displayed using an Overheard Projector. From there to pico-projectors!
Looking at that second slide, not one of the departments named still exists:
IR and C&E became HMRC, DSS became DWP, DTI iterated a few times and is now DBIS, MAFF is now defra (and DECC).
