AG Barr, a Scottish soft drink manufacturer established in Falkirk, began to produce "Iron Brew" in 1901. During the Second World War, Iron Brew was no longer produced due to a lack of raw materials. This lack led to the creation of a list of companies still authorized to produce drinks, and AG Barr did not make it.When production started again in 1947, a new law forced Iron Brew to change its name because it was not literally brewed. The company chose the name "Irn Bru", which allowed them to keep the same pronunciation. In 1954, Irn Bru began to be sold in England and for the first time it was subject to exportation. In 1979, the first plastic bottle was produced. Before this date, the bottles were made of glass and were returnable. Thanks to its success, the brand has launched a diet alternative of the drink as well as an ice cream. In 1997, AG Barr acquired a label for the tartan combining the blue and orange colours of Irn Bru.
Advertising campaigns started as early as 1905 in newspapers, featuring great Scottish athletes of the time. In the 1930's, a comic strip advert was launched, introducing the characters of Ba-Bru and Sandy. This comic was abandoned in the early 1970’s, making it one of the longest running advertising comics. The drink is well known for its advertising campaigns. One of Irn Bru's best known slogans is "Made in Scotland from girders", in reference to its rust colour. Some advertising campaigns have caused controversy and complaints, especially a television advert in which a woman claims to love Irn Bru like the rest of her family "even though she used to be a man" and is seen shaving. Current adverts focus on people having a bad —but nonetheless funny from the viewer's point of view— experience, claiming "Irn Bru gets you through".
