In 1993, Al Ries and Jack Trout have defined the laws of marketing in The 22 Immutable Laws of Marketing (which is by the way a must read for any marketer). And while most of 90’s marketing ideas are not very accurate today (press and outdoor campaigns seem not to be enough and 2 for 1 sales strategy might not be the best sales strategy), the laws seem to last.
The idea for this article is to review those laws and see how they work today. I have found a lot of argue over the Internet whether the laws from the book work or not (ex. here and here). I will be very happy to listen what you thin about them.
