Other cool ticker symbols

By now, everyone has heard about us changing our stock symbol from SUNW to JAVA, a very shrewd move, very smart in my opinion. And it's not a new idea, either. Smart companies have been doing it for decades. It's very prestigious to have a single-letter symbol, for instance, so Citigroup grabbed C when Chrysler let go of it. US Steel was always X, symbolizing power and uniqueness. And using your flagship brand as your symbol has a long history, too. Perhaps the most famous: Anheuser-Busch's ticker symbol is BUD.
Some other cool tickers:
Southwest Airlines -- LUV
The Cheesecake Factory -- CAKE
The Boston Beer Co. (maker of Sam Adams beer) -- SAM
I got this info from this excellent 2005 article by Dan Fitzpatrick of the Pittsburgh Post-Gazette.
