Let’s imagine you painted a sign saying, the circus is coming to the town this Sunday.
THAT IS WHAT YOU CALL ADVERTISING
If you stick the same sign on the car and drive it into town
THAT IS WHAT YOU CALL PROMOTION
The same car drive to the city hall to visit the Major and local newspapers write about it
THAT IS WHAT YOU CALL PUBLICITY
And if the city of Major talks about the circus and the event
THAT IS WHAT YOU CALL PR
If the town citizens go to the circus and they spend money on food carts and entertainment booths
THAT IS WHAT YOU CALL SALES
And if you plan everything including advertising, promotion, publicity, PR, sales etc
