I've been following SpaceX recently so I thought I'd point out a few things about them in regards of breaking new ground.
The company went from being founded to launching its first commercial payload to orbit in about seven years. (Which seems pretty quick in aerospace timescales)
They're consistently delivering supplies to the ISS for about half the price of their competitor using the Dragon capsule which is also able to return cargo back to Earth.
The Dragon capsule was designed with carrying passengers in mind, and version 2 of the capsule which will be undergoing launch abort tests soon is scheduled to start taking astronauts up to the ISS in about two years or so.
It will also be capable of landing propulsively.
They've undercut the prices of all existing competitors significantly, making them scramble to design new rockets to match SpaceX's price, but they'll only be ready around 2020.
Meanwhile SpaceX has been testing reusing the rocket's first stage.
The upcoming mission to the ISS will have its first stage attempt to land on a barge at sea, with the ultimate goal being landing back at the launch site.
Elon claims a theoretical potential hundred-fold price reduction for launches, but even a ten-fold reduction would have a significant effect on the industry.
In the longer term, SpaceX has plans for much larger engines and spaceships, with the ultimate goal of landing on Mars and eventually enabling people to move to Mars for around $500K.
