Which of the following statements is true about the traditional tradeoff between the richness and reach of a marketing message prior to the development of the Web？
A、The larger the audience reached， the less rich the message
B、The smaller the audience reached， the less rich the message
C、Marketing messages had little richness
D、Richness was unrelated to reach
正确答案：A
答案解析：
Analysis of Option A：
Before the development of the Web， there were limitations in marketing communication channels. For example， mass - media advertising like television commercials or billboards could reach a large audience （wide reach）. However， due to time constraints （in the case of TV ads） or limited space （in the case of billboards）， the amount of detailed information （richness） that could be conveyed was relatively small. In contrast， more personalized communication methods like direct mail to a small， targeted group could include more detailed information （higher richness） but had a smaller reach. So， generally， the larger the audience reached， the less rich the message. This option is correct.
Analysis of Option B：
When the audience reached is smaller， it is often possible to be more detailed and provide a richer message. For example， a salesperson communicating with a single potential customer can tailor the message， provide in - depth product details， and answer specific questions. So， the smaller the audience reached， the less rich the message is an incorrect statement.
Analysis of Option C：
Marketing messages did have some level of richness depending on the communication method. For instance， brochures and catalogs could provide relatively detailed product information， so it is inaccurate to say that marketing messages had little richness. This option is wrong.
Analysis of Option D：
As explained above， there was a trade - off between richness and reach. They were related in that expanding the reach often came at the cost of reducing richness. So， the statement that richness was unrelated to reach is incorrect.
