Marketing books were invented 6000 years ago.
You don't believe me?
Here is the proof:
6000 years ago a man had a brilliant idea:
He made a spear.
A powerful invention – but his fellow human beings were not convinced.
"This will never prevail," said the japan telegram screening experts.
So the inventor of the spear also invented marketing.
How?
He painted on a cave wall:
"6 Ways a Spear Can Save You from a Wild Boar"
A team of researchers has actually found this cave painting, which is dated to almost 4000 years before Christ and has been translated by archaeologists.
It is practically the first marketing book of all time.
From this we learn:
No matter how good your product is, you need marketing.
