It may be possible to see what projects a company has planned by using the Reverse IP tool, found at DomainTools. In case you weren’t aware, you can see what domain names reside on different servers by using this tool. By seeing the domain names registered by a particular company, you may be able to learn unreleased information about what projects (or type of projects) the registrant has in the works.
Unfortunately, this tool isn’t free, but is a part of your Domaintools membership, which I highly recommend. Other member tools such as the Whois History check are invaluable and can help determine a domain’s provenance when considering a purchase.
As reported on WebProNews.com this morning via another post on ResourceShelf.com, Google registered CouponGoogle.com on 9/13, and it is pointed to Google nameservers. It would only be speculation to predict what Google intends to do with the domain name, but speculation is half of the fun!
