The Herfindahl Hirschman Index of concentration is 1,820. Must now find out analogous figures for the UK…

Update: the HHI for the UK in 1993 [old data, using circulation, not market share] was 2723, so actually higher. Contrariwise, a 1993 Competition Commission report suggests that using revenue share, concentration is 1,611 (moderately concentrated, and less thna Italy).
