Beer is the world’s most widely consumed and probably oldest alcoholic beverage, it is the third most popular drink overall, after water and tea. The brewing industry is a global business, consisting of several dominant multinational companies and many thousands of smaller producers ranging from brewpubs to regional breweries. More than 133 billion liters are sold per year producing total global revenues of $294.5 billion in 2006. Imagine that.How do the breweries fight amongst themselves? With advertising. Not with flavor, not with taste, with advertising.
