Let me point you toward an impressive database that contains detailed histories of most companies. It is theInternational Directory of Company Histories. It's a little hard to search through but has everything you are looking for. You may have to click through the pages to find the exact company you are looking for. The information here is bar none the most comprehensive we have available for histories of companies.
For a more summarized and brief history of companies you may be interested in checking outEBSCO. In EBSCO you have access to many databases. Through searching I have found the only database in EBSCO with Company Histories is Dataminer. You will want to narrow your search to that database.
