His empire includes the Daily Mail, the Mail on Sunday and the morning free paper Metro. And of course the world's biggest newspaper website, Mail Online.
The site is read by an estimated 6.5 million unique visitors daily, and last year generated £16m. It may seem modest but year-on-year growth was 69% in the second quarter and Mail Online is on course to hit revenues of £45m in the year to September 2013, offsetting declines at the print titles.
It's all looking good for Rothermere – Jonathan Harmsworth – who chairs DMGT and controls the majority of its voting stock; his wealth was estimated at £760m in the Sunday Times Rich List.
Despite making what our panel said was "his first genuine editorial appointment" in Mail on Sunday editor Geordie Greig, his relatively low placing reflects his hands-off approach to his titles; the Mail's main influence is of course Paul Dacre. Rothermere also made an assured appearance at the Leveson inquiry on the same day as Andy Coulson.
"Still in 40s, he's really smart," said one of our experts. And given the Mail's strength and the company's stability he is likely to creep up the list.
