This is no surprise to java junkies, but coffee is big business. McDonald's (NYSE: MCD) and Green Mountain Coffee Roasters (Nasdaq: GMCR) each rake in more than $1 billion in annual revenue from coffee alone. Dunkin' Donuts (Nasdaq: DNKN) can't reach those figures, but is known for its java and says it's No. 1 in iced-coffee sales.

Each of these companies no doubt lifted a mug in celebration of Starbucks' (Nasdaq: SBUX) recent decision to raise its prices.

The king of caffeine does more than $10 billion in annual sales. In light of the still-struggling global economy and penny-pinching consumers, could Starbucks' price hikes really cause it to lose market share to competitors?
