John Campbell is credited for the first newspaper, the "Boston News-Letter", which appeared in 1704. The paper was known during the revolution as ""Weeklies"". The name came from the 13 hours required for the ink to dry on each side of the paper. The solution was to first, print the ads and then to print the news on the other side the day before publication. The paper was four pages long having ads on at least 20%-30% of the total paper, (pages one and four) the hot news was located on the inside. The initial use of the "Boston News-Letter" carried Campbell's own solicitations for advertising from his readers. Campbell's first paid advertisement was in his third edition, May 7 or 8th, 1704. Two of the first ads were for stolen anvils. The third was for real estate in Oyster Bay, owned by William Bradford, a pioneer printer in New York, and the first to sell something of value. Bradford published his first newspaper in 1725, New York's first, the "New-York Gazette". Bradford's son preceded him in Philadelphia publishing the "American Weekly Mercury", 1719. "The Mercury" and William Brooker's "Massachusetts Gazette", first published a day earlier.
