I've been set this piece of homework for a job interview and, well I'm a little bit stumbed. 500 words on a recent marketing campaign, can use images/music/video etc. but the catch is "...The only other stipulation is that we’d like this not to be about any form of culture, i.e. no marketing campaigns for films, music, arts etc."

Aren't most blogs about these, maybe I'm jsut being a bit myopic, but has anyone seen anything particularly inpiring/interesting around that might not fall into this category?

Any suggestions would be appreciated.
