Paul Block was president of Paul Block and Associates and publisher of the Pittsburgh Post-Gazette and Toledo Blade.

Block Communications Inc. is an American privately held holding company of various assets, mainly in the print and broadcast media, based in Toledo, Ohio. The company was founded in 1900 in New York City when Paul Block, a German-Jewish immigrant who came to the United States in 1885, formed an ad representation firm for newspapers. The Block empire grew to encompass many newspapers on the east coast of the US, however with the Great Depression in the 1930s came the loss of all but three properties: the ad representation firm, the Pittsburgh Post-Gazette, and the Toledo Blade. After Block's death in 1941, his children took over the company. They eventually passed it on to their grandchildren, who continue to operate it to this day.
