When Americans make buying decisions today, they prefer to do so in conversations with people they respect rather than through one-way advertising communications. For most people, the first step in the buying process is to ask someone what they think, and then to test-drive those ideas and suggestions with others before making a purchase decision. The availability of e-mail, chat groups and bulletin boards on the Internet enhances this trend substantially. Therefore, to forecast what direction consumer preferences will move in the future, it isn't necessary to research the entire population. Instead, know and understand what the "influential people" are thinking and you'll have a pretty good leading indicator on what the population as a whole will say. 感謝您對大師輕鬆讀的愛護，並且全力支持您合理地使用我們為您精心編製的內容。希望未來可以提供您更方便更友善的服務。
