Carnival Corporation Ltd.
The world's largest cruise company, it runs eight cruise lines—Carnival, Princess, Cunard, Holland America, Costa, AIDA, P&O, and Seabourn—sailing millions of vacationers to destinations across the globe. It began in 1972 when Ted Arison founded Carnival Cruise Line with a single converted ocean liner, the Mardi Gras, which famously ran aground on a sandbar during its very first voyage and turned into an accidental 24-hour party at sea.
