 Newspaper publishing became much more heavily professionalized in this era, and issues of writing quality and workroom discipline saw vast improvement.This era saw the establishment of freedom of the press as a legal norm, as President Theodore Roosevelt tried and failed to sue newspapers for reporting corruption in his handling of the purchase of the Panama Canal.Still, critics note that although government's ability to suppress journalistic speech is heavily limited, the concentration of newspaper (and general media) ownership in the hands of a small number of private business owners leads to other biases in reporting and media self-censorship that benefits the interests of corporations and the government.
