Millward Brown's annual BrandZ Top 100 Most Valuable Global Brands ranking is out. Just like last year, tech brands dominate the top positions. 

Google regained the top spot from Apple, while Facebook and Amazon entered the top 10 for the first time. What's interesting, though, is what the rankings tell about the shift in consumer dynamics.

As the power of digital communication has grown, tech firms have replaced consumer goods and other sectors at the top of the listing. In a world where customers are less loyal, more demanding and have an endless pool of brands to choose from, it will be interesting to see what the top 10 will look like in ten years' time.
