Transportation app Uber is seen on the iPhone of limousine driver Shuki Zanna, 49, in Beverly Hills, California, December 19, 2013. Uber has entered more than 60 markets, ranging from its hometown of San Francisco to Berlin to Tokyo. Leaked financials in December indicate that the company, which began connecting passengers with drivers of vehicles for hire about 3-1/2 years ago, is generating $200 million a year in revenue beyond what it pays to drivers.
