"A Professor was explaining Marketing to MBA students.
You meet a gorgeous girl at a party.......1. You go to her and tell her, "I am very rich, marry me", that's Direct Marketing.
2. Your friend goes to that girl and pointing at you tells her, "He' is a very rich guy, marry him", that's Advertising.
3. This gorgeous girl walks up to you and tells you, "you are very rich, will you marry me ? ", that's Brand Recognition
4. You tell her, "I am very rich, marry me" and she slaps you, that's Customer Feedback
5. You tell her, "I am very rich, marry me" and she introduces you to her husband, that's Demand & Supply Gap
6. Even before you can tell her, "I am very rich, marry me", your wife arrives, that's Restriction from Entering New Markets !!!
