"Twenty years on from our first report, customers today are more informed, more connected and more demanding than ever before through a combination of wealth of choice, erosion of loyalty, and shifting frames of reference wanting immediacy, abundance and intimacy - all at the same time," Charles Trevail, global chief executive officer of Interbrand, said in a press statement.

The report cited some of the biggest changes over Interbrand's 20 years of surveying, including the fact that only 31 of the brands from 2000 remain on the list today, including Disney, Nike, and Gucci. At the same time, only Coca-Cola and Microsoft have maintained top 10 spots.
