Grabbing a cab was made even easier when Uber rolled around, allowing users to book a ride with just a touch of a button. It was created by Garrett Camp and Travis Kalanick in 2009, before going on to become a multi-billion-dollar business and a household name across the world.

In 2014, Chinese internet-search titan Baidu Inc. made a big investment of over $600 million to help Uber expand into China. The partnership was mutually beneficial, as Baidu wanted to use Uber to grow its mobile payment service. It was a match made in heaven.
