The increased demand by viewers for news reporting led to the advent of "the age of reporting" in the TV world. News programs became the main arena in the ratings competition, and the networks all competed in improving and expanding their news-reporting apparatuses in the attempt to strengthen their news programs. At the same time, the advent of "the regional age" led to an increased need for local news reporting by regional TV stations, especially of political news directly related to the daily lives of local citizens. A tendency can also be observed for the success of local news programs to raise the overall ratings of the station. However, size limitations on news-reporting staff have meant that most local stations are faced with the dilemma of being unable to carry out adequate news-reporting activities.
