Most beer drinkers will be aware that the American brewer named Budweiser (now owned by the Belgian based multinational Anheuser–Busch InBev) took its name from a long–established Czech company with which it has no connection. These two companies have a long and complicated history of competition for the use of brand names and advertising slogans in various parts of the world, and this one is no exception.
According to Wikipedia, the Czech Budweiser 'has been called "The Beer of Kings" since the 16th century. Adolphus Busch [co–founder of the American brewing company, in 1876] adapted this slogan to "The King of Beers."'
A Google search for "King of Beers" led me to this site, which appears to be that of a local paper based in Portland, Oregon. It takes the story of the dispute between the two companies over the use of the slogan a few stages further. I started reading, but to be honest I very quickly found myself losing the will to live and so I stopped.
