One of the things I'll be doing in London is studying ad campaigns and talking to people about them. In addition, I will be looking to see how the same products are marketed in the US and in the UK. I am curious as to what ads stand out, what they are advertising, are they effective, do you like / loathe them....and that sort of thing. I would love to have an idea of what to expect when I arrive. Thanks to all in advance.
