[2] At the time of establishing the New York Daily Sentinel, Day had just one year of experience working for commercial newspapers.
Day wanted the paper to be available to as many people as possible, and formally established the Sentinel in 1830, with a low start-up cost supported by Lynde and Stanley.
Lynde and Stanley would later launch The New York Transcript in 1834, the year after the Sentinel ceased publication.
By the middle of the 19th century, The Sun was the most widely circulated American newspaper, and, priced at one cent per copy, it was part of what became known in New York City as the Penny Press.
George Henry Evans, founder of The Man and inspiration for the Homestead Act of 1862, eventually bought the paper from Day.
