What is Uber? How does it work?

Uber Technologies Inc. is an American multinational online transportation network company headquartered in San Francisco, California.It develops, markets and operates the Uber mobile app, which allows consumers with smartphones to submit a trip request which is then routed to Uber drivers who use their own cars. As of May 28, 2015, the service was available in 58 countries and 300 cities worldwide.

Since Uber’s launch, several other companies have copied its business model, a trend that has come to be referred to as “Uberification” (Wikipedia).
