The Oceanic Steam Navigation Company, more commonly known as the White Star Line, was a British shipping company. Founded out of the remains of a defunct packet company, it gradually rose up as one of the most prominent shipping lines in the world, providing passenger and cargo services between Britain and the United States, Canada, South Africa, New Zealand and Australia. Today it is most famous for the innovative vessel Oceanic of 1870, the Olympic class ocean liners, including the ill-fated liners RMS Atlantic, RMS Republic, RMS Titanic and HMHS Britannic,. Despite its casualties, the company retained a prominent hold on shipping markets around the globe before falling into decline during the Great Depression, which ultimately led to a merger with its chief rival, Cunard Line, which operated as Cunard-White Star Line until 1950. Cunard Line then operated as a separate entity until 2005 and is now part of Carnival Corporation & plc. As a lasting reminder of the White Star Line, modern Cunard ships use the term White Star Service to describe the level of customer care expected of the company.
