The newspaper group of a certain city encountered difficulties in operation and went to a consulting company for assistance. The consulting company sent Dr. Zhang to investigate the period of the publishing of the target newspaper. There is a morning paper in the morning, a daily newspaper in the morning and an evening paper in the afternoon, all of which are not prepared for night. Dr. Zhang suggested that they should set up a Metropolitan Night News to occupy this market.
The period of the publishing of the newspaper and the reading time of the reader being different can properly point out the problems in Dr. Zhang's analysis.
