These companies are researched and placed on this wiki when I find them referenced in advertisements from old magazines and newspapers. Information is found in old books and online.
It is important to note that while most information is trusted as true, some dates may be incorrect because of conflicting or faulty sources.
If anyone who has information concerning a missing piece of information for a company, please leave a comment on that page. Missing information only refers to when the company was founded, by whom, and where; when and if it was acquired by a different company, if it merged with another company, and when or if it went out of business; and finally if it changed its corporate name. Information concerning products manufactured by the company and advertisements for the business are to be only added by myself.
