The amount of companies with a huge customerbase is ever rising. When I wrote my book I identified Vodafone and Citibank with 300 million customers. The amount of companies/brands that operates world-wide, has a shred customer database worldwide and which can help customers worldwide without having to create a new account will happily continue to rise in the coming years. The waiting is for the first company with a billion registered users.
