These are tech vendors with billions in profits that are largely ignored by business press, and there are tech categories with enormous worldwide revenue (enterprise categories in particular like storage, virtualization, network infrastructure) that are barely even acknowledged.
Oracle ($22 billion in revenue, $5 billion in profits) only cracks the top 10 companies by coverage for one of the eight publications examined: Fortune. Cisco ($40 billion in revenue, $8 billion in profits) didn't make it on anyone's top 10 list. IBM ($100 billion in revenue, $12 billion in profits) wasn't even in The New York Times' top 20, and was No. 19 for The Wall Street Journal.
