Media Advertising Information Tracking System (MAITS) is an internet-based newspaper advertisement monitor and analysis system, developed by us. This system could provide an analysis for us to study the advertising volume change by different media, by industries, and the advertising revenue and market share. With this analysis, the advertising department could easily understand the media and competitive media’s situation, whether the advertising makes profit or not, what the leading advertising industries are, what the vulnerable advertising industries are, whether the business target could be met or not.
