Uber is a disruptive technology that has significantly impacted the transportation industry. It began as a mobile app in 2009 that allowed users to hire drivers for rides, and has since expanded to include food delivery and additional services. Uber has disrupted the taxi cab industry by taking customers and losing them money due to competition. It has also decreased the number of people using public transportation systems. As a result, some areas have banned Uber to protect their local transportation industries.
