Sorry, a history doesn't exist.

Thanks Jay.

Remember it changes the company name in database setup if someone changes the name in Common Services Company Profile so you might be able to see the changes in there in CSCOM as to who was the last person who edited it, looking back through backups if the last change isn't the one you're looking for - that might help.  Audit logger from Pacifictech would also give you that - just on the basis of who changed the common services company profile, not in database setup.
