Final answer:
The New York Sun, founded by Benjamin Day in 1833, was the first penny paper, offering affordable news and marking a pivotal change in print media.
Step-by-step explanation:
The New York Sun is credited as being the first penny paper, which marked a significant change in the newspaper industry by offering affordable news to the wider public. Founded by Benjamin Day in 1833, the Sun capitalized on advances in printing technology and improved transportation infrastructure to mass-produce and distribute its newspapers, which were sold for a penny per issue. The availability of inexpensive newspapers like the Sun broadened the reach of print media and reflected changes in society, including a more literate public and the increasing importance of keeping citizens informed. Over time, the content of newspapers diversified to include a mix of gossip, news, and educational materials while journalistic standards evolved with papers like the New-York Tribune setting a precedent for high-quality journalism.
