Question: can big companies innovate? or is it just fine for them to just iterate? 

Answer: Generally, business has to innovate. That's where the differentiators are established--and if you don't have an edge, then you don't have a viable model for sustaining growth.\n\nIteration may play a lead role in their R&D process, but markets are so flexible and fluid that true market share, and loyalty will be captured by the innovators for the longer horizon.
