10. De Beers – A Diamond is Forever
Prior to the De Beers marketing campaign, a diamond ring was unheard of in terms of engagements and weddings. The diamond didn’t even have any real value until it was promoted by the De Beers marketing campaign. The iconic slogan “A Diamond is Forever”, put De Beers over the top and now diamond rings have become a cultural necessity all around the world. That along with the monopoly of the company in the diamond market launched them to success.
