Having spent most of my life in the Bay Area, my view of what constitutes "big business" skews heavily towards tech. I'm sure folks from New York would say financial services and folks from Los Angeles would say entertainment. It blew me away when looking at the latest Forbes report on the world's most profitable corporations that Oil & Gas Operations dominated the top 6 by a healthy margin. What's more jaw dropping are the revenue numbers. I thought Microsoft's $62 billion was a lot but it's dwarfed more than 7 times over by ExxonMobil and Royal Dutch Shell. Just goes to show how far we need to go to ween ourselves off petroleum based products.
