Before the 1830s, newspapers were expensive and mostly for rich political nerds. Benjamin Day changed the game by making the paper smaller, using a faster press, and selling it for just a penny.
The Penny Press turned newspapers into the first true form of mass media.
The text states that Day slashed the price of the paper to a penny and utilized a two cylinder steam engine to massively increase production.
Because the paper became affordable and shifted its focus to human-interest stories rather than just dry politics, it reached the average person for the first time. This expanded the audience from a small elite group to the general public, creating the massmarket journalism we recognize today.
