Hansson worked at Idrottsbladet from 1957 to 1962, at Strömbergs förlag from 1962 to 1965 and at Radiosporten, the sport section of Sveriges Radio from 1965 to 1969, before switching to Sveriges Television (SVT) in 1969.
[1] As a journalist he has covered several international sporting events such as the FIFA World Cup and the Olympics.
He was the live commentary when Thomas Ravelli saved the decisive penalty in the 1994 World Cup quarter final penalty shootout between Sweden and Romania; a moment that was later dubbed the biggest Swedish sports moment of the 20th century.
Racialist controversy arose in 2012 when he sat in the commentator booth at Råsunda Stadium and was heard saying 'not another black player' in a derogatory manner to an AIK substitution.
