It is clear from the passage that newspapers ----.

A newspaper is a daily or weekly publication
containing news and comments on the news. Newssheets
appeared after the invention of printing and
were introduced in 1609 in Germany and in 1616 in
the Netherlands. In 1622, the first newspaper
appeared in English. Improved printing and cheap
paper and a growing reading population led to a
growth in newspapers, but they were expensive. In
the 20th century, production costs fell with the
introduction of new technology.
