never mess with the distinctive brand assets
Apparently this funny and insightful ad for Marmite has caused something of a minor kerfuffle in the UK as some feel that it's humour trivialises the work of animal protection services.
As a result more people will have noticed it so it's all gravy for Marmite.
The real scandal however, as Doddsy correctly points out, is the gratuitous and completely unnecessary display of the Unilever logo on the end frame instead of the Marmite logo.
Rule number one is never mess with the distinctive brand assets, and certainly never replace them in the key moments (remember the peak-end rule) with meaningless ones.
Schoolboy error.
