In 2008, successful programmers Travis Kalanick and Garrett Camp went to a conference in Paris and found that it was incredibly difficult to find a taxi there. Running into such a widespread problem made the men think. The following year, UberCab was launched in San Francisco. Celebrities provided good advertisement: Ashton Kutcher, Edward Norton, and Jay-Z used the service.
Today Uber is the number one taxi service in the world. The online service also has numerous daughter applications, including the food delivery service UberEats.
