Princess Cruises is a cruise line based in Santa Clarita, California, in the United States and incorporated in Bermuda. Previously a subsidiary of P&O Princess Cruises, the company is now one of ten cruise ship brands owned by the worlds largest cruise ship operator the American/British Carnival Corporation & plc and accounts for approximately 19% share of its revenue. It is part of Holland America Group, which controls the three Carnival brands based on the West Coast of the United States. The lines ships cruise worldwide and are marketed to both American and international passengers. The company was made famous by The Love Boat TV series, in which its ship, Pacific Princess was featured. In May 2013, the brand new Royal Princess became the flagship of Princess Cruises, and was joined by her sister-ship Regal Princess in May 2014 and will be joined by Majestic Princess in the spring of 2017. Princess Cruises began in 1965, when founder Stanley McDonald chartered Canadian Pacific Limiteds Alaska cruise ship Princess Patricia for Mexican Riviera cruises from Los Angeles during a time when she would have usually been laid up for the winter. However, Princess Pat, as she was fondly called, had never been designed for tropical cruising, lacking air-conditioning, and Princess ended her charter in favor of a more purpose-built cruise ship Italia. Princess, who marketed the ship as Princess Italia, but never officially renamed her, used the ship to inaugurate their Mexican Riviera cruises out of Los Angeles and did not receive the Princess logo on her funnel until 1967.
