First movers are companies that are the first to enter the market with a new product or new service to sell.

Early followers are companies that are early to market with a product to sell, but they are not the first. Late Entrants are companies that enter the market late with a product to sell.

Another example is eBay. eBay was founded in 1995 and became a notable success story. It is the first e-commerce corporation that manages an online auction and shopping website in which people and businesses buy and sell a wide variety of goods and services worldwide. eBay went public in 1998, the founder became instant billionaires. One of the fastest first-mover successes. There are a few that weren't successful, for example, Sony Betamax.

What are some possibilities that could lead to failures in both scenarios?
