[4] In 1835, Day's Sun was responsible for publishing a story written by Richard Adams Locke about life on the Moon that was fictional, but was received by the general public as fact.

Day is also credited for importing to the United States the London Plan, a system of newspaper distribution largely antiquated today in which the paper carriers buy newspapers in bulk from the publisher and sell the papers to the reading public for a profit.

In 1842, he created the Brother Jonathan, the first illustrated weekly in the U.S., which he ran for twenty years.

[5] Day constantly quarreled with George Wisner over the publication of abolitionist articles.

From The New Yorker:[6] The American newspaper business as we know it was born on September 3, 1833, when a twenty-three-year-old publisher named Benjamin Day put out the first edition of the New York Sun.
