In the 19th century, Emerson and some other writers taught readers a theory called self-help theory. In these people's eyes, a person with personality must have a full brain. Under the guidance of this kind of thinking, in order to gain the respect of others, it is necessary to extensively study outstanding works in cultural history in leisure time. At the same time, it is also necessary to be familiar with philosophy, theology, and major political events worldwide. This trend has shaped U.S. journalism in more than a century. During those decades, magazines focused on promoting classical opera, high art, and religious theology, rather than movies or common sense of public health.
