To add on top of pri_dk’s point, it’s more than just the initial invention/discovery. Innovation comes at all stages, just the the initial discovery. Xerox invested the mouse and GUI. But who here thinks OSX, Windows, Android, iOS, etc. won’t exist without Xerox initial innovation. Xerox invented it, but they didn’t have the vision and the execution to bring that invention to the masses. Microsoft did that with Windows. They took the initial invention and found innovative ways to use that initial invention to bring PC to the masses and changed the whole landscape. Even after a product get released, innovations continue to occur. After all, iOS wasn’t the first mobile smartphone OS, but who here thinks Apple wouldn’t have come up with iOS if Microsoft didn’t come up with Windows Mobile or Palm with PalmOS? The smartphone market wouldn’t be where we are today if Apple didn’t innovate and came up with iOS. Now, Android have taken over the torch. Bottom line is, innovation happens everywhere and all the time at every stage of the development. It not just about the initial discovery.
