Park Rowgue (Park Row + rogue)

Park Row in Manhattan is just across from City Hall. In the late 19th century, so many newspapers located in Park Row that it was dubbed “Newspaper Row.”
 
Newspaper entertainment columnist Walter Winchell (1897-1972) coined the name “Park Rowgue” for a newspaper man. “Park Rowgue” has been cited in print since at least 1928, but the term quickly became obsolete when New York’s major newspapers began to leave Park Row and locate in midtown.
     
 
Wikipedia: Park Row (Manhattan)
Park Row is a street located in the Financial District of the New York City borough of Manhattan. It was previously called Chatham Street and during the late 19th century it was nicknamed Newspaper Row, as most of New York City’s newspapers located on the street to be close to the action at New York City Hall. The street runs east-west, sometimes called north-south because the western end is nearer to Downtown.
