Coca-Cola was introduced in 1886, patented in 1887, registered as a trademark in 1893 and by 1895 it was being sold in every state and territory in the United States.

You may use introspection in Graph API by adding metadata field while requesting object information from Graph API to discover the type of object:

http://graph.facebook.com/40796308305?metadata=1

This will return additional object metadata including type property which will be according to Object Type one of: user, page, group, status, photo, etc…
