Evil Incorporated: 10 Pentex Subsidiaries

From the back of the book:

Pentex is not, strictly speaking, a company. Pentex is a huge network of interlinked companies that are joined together through both formal and informal networks, bent toward similar goals. There is no stock market entry for “Pentex” used by traders, and it isn’t a single conglomerate one can buy stock in, or get a job working for. Rather, it is a hydra made of capitalism. It bears a thousand names, and every time someone manages to shut one connected company down, it seems like two more rise to take its place before the market opens on the next business day.
