Publicist style became discernible as a separate style in the middle of the 18th century. It also falls into three varieties, each having its own distinctive features, which integrate them. Unlike other styles the publicistic style has spoken varieties, in particular, the oratorical substyle. The development of radio and television has brought into being a new spoken variety, namely, the radio commentary. The other two are the essay (moral, philosophical, literary) and articles (political, social, and economic) in newspapers, journals and magazines.
