A pretty girl

A famous professor at Harvard University told students about the concept of marketing in class. To make it easy to understand, the professor cited examples in his life to explain:

<1> at a party, you saw a pretty girl. You stepped forward and said to her, "I have a lot of money. Marry me !" This is called direct marketing.

<2> when you saw a beautiful girl at a party with a group of friends, one of your friends came to her and pointed to you and said, "He has a lot of money. Marry him !" This is called advertising marketing.

<3> when you saw a pretty girl at a party, you stepped forward and requested her phone number. The next day, you called her: "Hi, I am rich. Marry me!" This is called telemarketing.

<4> when you saw a pretty girl at a party, you stood up, finished your tie, and walked up to her to bring her a drink. When she was about to leave, you open the door for her. When her bag accidentally fell, you picked it up for her and drove her for a ride. At this time, you took the opportunity and said, "Yes, I have a lot of money, would you like to marry me?" This is called PR.

<5> when you saw a beautiful girl at a party, she took the initiative to come to you and said, "I know you are rich. Can you marry me ?" This is called brand recognition.

<6> when you saw a pretty girl at a party, you walked up to her and said to her, "I have a lot of money. Please marry me !" She slapped your face. This is customer feedback.

<7> when you saw a beautiful girl at a party, you walked up to her and said to her, "I have a lot of money. Please marry me !" At this time, she introduced her husband to you. This shows the gap between supply and demand.

<8> when you saw a beautiful girl at a party, you walked up to her and said, "I have money, please marry me!" She went with him. This means that competitors are encroaching on your market share.

<9> you saw a pretty girl at a party. Before you could say, "I have a lot of money, please marry me." Then your wife arrived. This is the access restriction for the new market.
