I want to keep track of all the large, multi-national companies and brands that have launched their .mobi (if they use their .mobi to forward to another domain, then they must be advertising their .mobi site to be included), and categorize them by industry to organize it better. After all, these large companies have the power to make .mobi mainstream by simply advertising their .mobi site to their millions of customers.

I'll start the list and will edit it as it grows. Let's try to stick to very large, well-known corporations and important organizations that most people know.
