Analyzing transformational new businesses with innovator advantage

Think of some transformational new businesses such as Starbucks, Blue Apron, or Amazon etc
How was each business different from what came before? What was similar to what came before? Scale them in terms of “newness” from truly transformational (5) to substantial (1). Explain your rationale.
Was there an innovator advantage? Explain your answer. If there was an innovator advantage, how long did it last?
Where did the idea for the business come from? If you can’t find this information, speculate.
