From Ohio History Central
A number of newspapers were published in Cincinnati, Ohio, during the first half of the nineteenth century. The Cincinnati Enquirer, began publishing a daily paper on April 10, 1841. At that time, the paper was not published on Sundays. The Enquirer became one of the first newspapers in the United States to publish a Sunday edition on April 20, 1848. From the beginning and for much of its history, the newspaper generally reflected the views of the Democratic Party. John McLean's family owned the Enquirer until the early twentieth century.
The Cincinnati Enquirer changed owners a number of times in the past century. It became part of the Gannet newspaper chain in 1979.
