Viscount Rothermere, as he is known, assumed leadership of the Daily Mail & General Trust (DMGT) newspaper conglomerate–which includes brands like The Evening Standard, Metro, and Euromoney from his late father in 1998, when he was just 30 years old. They have websites that possess the same gabby personality and attracts around a hundred million visitors every month because of their quickly written blog posts that usually involves entertainment and politics. Harmsworth was able to turn a notable page in the family history book in 2009 after selling The Evening Standard to Russian Alexander Lebedev.
A decade later he’s proved adept at guiding DMGT in a shrinking U.K. newspaper market. Under his leadership, the group launched the free daily Metro newspaper now copied around the world and has been growing its insurance and property arms. Jonathan Harmsworth currently has an estimated net worth of $1.1 billion.
