While the advertising world is still wondering just how cynical, colonial and faux-real that new Whopper ad/documentary is, I prefer my campaigns to be a little more subtle.
Have a look at how agency BBH is trying to revive interest in Tango with a campaign called Do the Can Fist. The full-length ad is here or on production company’s Knucklehead’s website, but also check out the Save Tango website, which seems to complement the whole vibe pretty well.  
I’m sure Tango wasn’t even doing that badly, but that underdog role suits it just fine. Made me smile.
