现代的广告发源于古老的“吆喝”,而最古老最原始的事情中往往蕴含着最朴素最深刻的道理。在商品需求和购买能力都极低的自给自足的农耕社会,要想沿街叫卖掉一件手捏的面人或一份可口的小吃,其难度都不亚于今天的新产品推销。因为没有人能知道在一个人家众多的村落中,有哪家人能有兴致给自己孩子花得起这份闲钱。于是一个叫卖者需要用他的吆喝来解决,并完成卖出东西所必须解决的前后相继的两个问题:一是如何将混杂在众多人家中为数不多的几个潜在的消费者吸引到自己的货台前?二是吸引之后如何说服他们完成购买? Modern advertising originated in the ancient “shout”, and the oldest and most primitive things often contain the most simplest and most profound truth. In a self-sufficient farming community with extremely low commodity needs and purchasing power, selling a handful of noodle or a delicious snack along the street is as difficult as selling a new product today. Because no one can know which of the many villages in a family is interested in spending the spare cash for their children. So a hacker needs to use his shout to solve and complete the sale of things must be solved before and after the two problems: First, how many people will be mixed in a small number of potential consumers to attract their own The second is to attract how to convince them to complete the purchase?
