I'd say the Bay Area has a pretty diverse economy.
The tech industry is of course the biggest sector (including computer stuff and other electronics, internet stuff, and biotechnology), but the Bay also has a large financial sector (Well's Fargo, Bank of The West, Charles Schwab, Bank of The Orient, First Republic Bank, PayPal, the US Mint, etc), health care/biomedical/pharmaceuticals (McKesson, Kaiser Permanente, Genentech, Gilead Sciences, etc), construction/engineering (Bechtel, Webcor, Gensler, Swinerton, URS, T. Y. Lin International), food (wine production, Ghirardelli, C&H Cane Sugar, Del Monte Foods, Columbus foods, PowerBar, Clif Bar, Odwalla, Jamba Juice, Black Angus Steakhouse, Shasta Beverages, See's Candies, Jelly Belly, Peet's Coffee, Häagen-Dazs Ice Cream, Dreyer's Ice Cream, etc), energy (PG&E, Chevron + 5 sizable oil refineries), retail and apparel (Gap, Levi Strauss & Co., Ross stores, Orchard Hardware, Safeway, Old Navy, etc, the North Face, Bebe, Jansport, etc) entertainment (Pixar, Lucasfilm, Electronic Arts, Netflix, Pandora, Dreamworks Animation, Sony Computer Entertainment, Dolby Laboratories), transportation (Gillig Corporation, Virgin America), manufacturing (Tesla Motors, Clorox + a bunch of the aforementioned electronics, food, and clothing stuff) and of course tourism is big too.
It's kind of confusing trying to get this info from Wikipedia, in terms of the different categories and what they should be called, but I tried.
This is one topic where a ranking of cities would actually be interesting.
