The story
Associated Newspaper Ltd was established in 1905 by brother newspaper barons Alfred and Harold Harmsworth. When Alfred died in 1922 without an heir, Harold Harmsworth acquired his controlling interest in Associated Newspapers for £1.6 million, and the next year bought the Hulton newspaper chain, which left Associated Newspapers in control of three national morning newspapers, three national Sunday newspapers, two London evening papers, four provincial daily newspapers, and three provincial Sunday newspapers.
Harold retired as chairman of Associated Newspapers in 1932 at the age of 64, and his son Esmond took over that role. He served as chairman until 1971, after which he assumed the titles of President and Director of Group Finance, and chairman of Daily Mail & General Trust Ltd, the parent company, from 1938 until his death. Harmsworth ran the businesses with sufficient skill that they remain firmly under family control today, majority ownership being voted by his grandson, Jonathan Harmsworth, 4th Viscount Rothermere (and a significant minority by Vyvyan Harmsworth, the 2nd Viscount's son by his third marriage). Jonathan Harmsworth is the chairman of the Daily Mail and General Trust (DMGT). Associated Newspapers changed its name to DMG Media in 2013.
In January 2022, DMGT delisted from the London Stock Exchange following a successful offer for DMGT by Rothermere Continuation Limited.
Associated-Rediffusion
In February 1954, with the passage of the Television Act 1954, Associated Newspapers joined forces with Taylorfilms and Rediffusion (the latter being a division of BET plc) into forming Associated-Rediffusion, winning the rights for London's weekday ITV service. They began broadcasting on 22 September 1955. During the partnership's first year, Associated-Rediffusion was losing money so fast that it was financially suffering; However, Associated-Rediffusion had managed to recover its financial security completely by October 1958. However, Associated-Rediffusion eventually lost its rights into broadcasting within London during August 1967.
