Harvey Firestone sold a lot tires to Henry Ford (who sold a lot of cars).
No great revelation that the rise of Facebook, Twitter and other social media forever changed the practice of marketing. The principles and best practices, however, are steadfast.
For the really great brands and merchants who have always done well by their customers, the tenets of great marketing and selling remain intact: treat people with the utmost respect, offer a product that delivers great value, follow up with great service and never take your customer for granted. This has been cornerstone of success from time immemorial. The so-called best practices of social media today–cultivation of one-on-one relationships, transparency, conversation, etc.–were at work when Harvey Firestone was selling tires to Henry Ford and the pharmacist at the corner drugstore had personal concern for his neighborhood’s family health.
Autodesk changed the practice of architecture but the principles of structural engineering didn’t change. And the principles of effective marketing are same in the era of Zuckerberg as they were in the time of Gutenberg.
