Last week I was forwarded an email with various “mashups” of Cadbury and Nestle brands.

Both Cadburys and Nestle are keen to reignite interest in their products and are relaunching some of their old brands (see my interview with branding expert Jonathan Gabay on this).

I am not at all suggesting that this viral was a contrived marketing effort, but it leads to the question of whether brands properly explore the option of marketing online with their competitors.
