The schwa Corporation was invented by Bill Barker, presumably in the book "the World Operations Manual" or some previous work of his.
The World Operations Manual is a spoof both on conspiracy theory and the machiavellian uber branding we all face. Information is catch-as-catch-can at this point. The trail is cold, so it'll take some pretty knowledgeable folks to help me find information regarding this. Thanks for your time.
