This ask here sort of answers your question! 

Basically, the editor, Joseph Pulitzer II, was the son of Joseph Pulitzer who was known for his crazy sensationalist headlines and yellow journalism tactics. He carried on in much the same vein, except he added a bit more legitimacy and made sure to shun any “snake oil” advertisements and things like that. He did a really good job but he’s relatively unknown compared with his father and his son, Pulitzer III.
