It must get a bit dull being the world's leading brand. No need for inventive or expensive advertising campaigns when the product you're touting is quaffed by the bucketload by a significant proportion of the world's population. Consequently, Coke has plumped for world domination, focusing their advertising efforts on strong-arming the few remaining stragglers who haven't embraced their sugary world view.

Are you one of the non-believers? Father Cokemas is coming to get you…
