Credit card marketing in the US isn't all that different from credit card marketing in some places outside of the US. While the US has a uniquely large well-banked population in the market for particular credit card products, the card-issuers and/or the card-issuers affiliate partners outside of the US do plenty of the same kind of things that are being done in the US too -- even as the numbers and other factors mean a customization of the business model is part of the picture for those who do make a living out of blogging outside of the US too.
What is true from the bottom-up is true from the top-down too.
