6. Miller Brewing Company
Most famous beer: Miller Lite
Armed with a rare German yeast, Frederick John Miller first leased out the Plank Road Brewery in 1855. It took nearly 50 years, but by 1903 he was living the High Life... until 1975, when Miller realized they needed to Liten up. Then, in 2008, they joined forces with Coors, which was founded only 18 years after Miller in 1873, predating the super-team of The Avengers by four years.
