HELLO CITIZENS!love;;:)

There is a strong belief to be made that marketing is an overall positive for the economy. But good or bad may be a moot point as a further case can be made that, in any economic environment close to being a free MARKET SYSTEM, MARKETING MAY ARISE NATURALLY ANYWAYS!

CONSUMERS DEMAND IS THE MOST IMPORTANT THING A BUSINESS AT FIRST LOOKS INTO! CONSUMERS TASTE AND FASHION DIFFER AND CHANGE VERY OFTEN!
