After that, the data results obtained were then analyzed. Targeting the products launched by the companies, they were divided into seven aspects of positive evaluation and negative evaluation to engage in in-depth discussions, Internet Access, Service Price, Internet Services, Service Quality, Internet Speed, and Cable TV Network. Statistical charts and diagrams were then drawn. The charts and diagrams were interpreted to determine “Which company was the most popular and the least popular?”; “What are the reasons for good plan sales?”; and “What is the perspective of concern to users?” The word-of-mouth analysis of the data served as a reference for consumers when choosing an ISP. At the same time, the information served as an important indicator for the company to determine customers’ needs, thus making the research commercially valuable.In view of the abovementioned contents, the broadband products shall be the research focus.
