The British are frantically Googling what the E.U. is, hours after voting to leave it

The whole world is reeling after a milestone referendum in Britain to leave the European Union. And although leaders of the campaign to exit Europe are crowing over their victory, it seems many Britons may not even know what they had actually voted for.

Awakening to a stock market plunge and a precipitous decline in the value of the pound that Britain hasn't seen in more than 30 years, voters now face a series of economic shocks that analysts say will only worsen before they improve. The consequences of the leave vote will be felt worldwide, even here in the United States, and some British voters say they now regret casting a ballot in favor of Brexit.
