In the past 13 years, the number of free newspapers published in South America has grown from one to 16, Newspaper Innovation reported Friday.

In 1995, the only newspaper published in South America was MetroNews in São Paulo. By 2000 that number was up to six.

Currently 16 free daily titles are published in six countries, according to Newspaper Innovation.

In Central America, free dailies popped up in Mexico in 2000 and in the Dominican Republic in 2001. Five papers total are now published in both countries.
