The History of Advertising Trust (HAT) is a nationally accredited archive service established in 1976 to preserve the heritage of the UK advertising industry and make it available for study and research. Today the HAT archive is the most comprehensive collection of British advertising and marketing communications in the world. Over the past forty years the Trust’s collections have developed into a truly unique resource for advertising industry and brand heritage records. Archives of several major advertising agencies and industry professional bodies form the core of HAT’s collections, alongside ephemeral press, poster and commercials collections.
