Netflix has one product, but has enough profits to improve that one product to disrupt a whole industry. The product is an app with videos on your home screen with a subscription layer.
Looking too closely at others will hurt you. I’m sure Netflix could have looked at Blockbuster in 2009 and knew they had them beat.
Adding more would have been a mistake. They’d spend all this money to add more when what they really needed was simplification.
Why do you really want growth at all costs? It costs you profits.
