By the early 19th century, there were 52 London papers and over 100 other titles. In 1802, and 1815 the tax on newspapers was increased to three pence and then four pence. Unable or unwilling to pay this fee, between 1831 and 1835 hundreds of untaxed newspapers made their appearance. The political tone of most of them was fiercely revolutionary. Their publishers were prosecuted but this failed to get rid of them. It was chiefly Milner Gibson and Richard Cobden who advocated the case in parliament to first reduce in 1836 and in 1855 totally repeal of the tax on newspapers. After the reduction of the stamp tax in 1836 from four pence to one penny, the circulation of English newspapers rose from 39,000,000 to 122,000,000 by 1854; a trend further exacerbated by technological improvements in rail transportation and telegraphic communication combined with growing literacy.
