Uber & Rideshare Apps
Before the day and age of Uber, grabbing a taxi was the go-to mode of city transportation. Then, in 2010, Uber was released to the public and totally changed the game. There has been a lot of pushback with the app, especially with taxi drivers, but it's still extremely popular and probably one of the best inventions of the decade.
Postmates
Postmates really brought out the laziness in people. The app dropped in 2011 and changed how everyone looked at delivery services. Postmates didn't just deliver food, but groceries and other household goods that you might need. Basically, with Postmates, you never need to leave the house.
