Spain's four primary national free newspapers have decreased in circulation by 13 percent from January through October this year compared to the same period in 2007, Newspaper Innovation reported Tuesday.

Although circulation at 20 Minutos, Metro, Qué! and ADN was cut back in June and July, it was down even more in September and October (free dailies aren't published in August).

Currently, circulation is at 3.4 million, down from 3.8 million in 2007, Newspaper Innovation reported, citing data from PeriodistaDigital.

Metro is now in second place in free daily circulation, just after 20 Minutos.
