As a journalist, Mason's longest running association has been with The Guardian,[2] for whom he has been a staffer on the foreign and sports desks and for whom he is a regular obituarist.
[3] In the late 1980s, Mason was among a small coterie of British journalists focusing on writing about green issues, in particular on the role of business in fostering environmental and social change.
With Football Factory author John King, Mason was also co-founder of Two Sevens[5] small press magazine, which included one of the first ever interviews with Irvine Welsh.
In 2024, Mason abridged, edited and wrote an introduction to Charles Darwin's The Voyage of the Beagle (1839), excising most of the scientific content to recreate the book purely as a piece of travel literature.
