Southwest Airlines is actually a hybrid disruptor, for example. It initially targeted customers who weren’t flying—people who previously had used cars and buses. But Southwest pulled customers out of the low end of the major airlines’ value network as well. Charles Schwab is a hybrid disruptor. It stole some customers from full-service brokers with its discounted trading fees, but it also created new markets by enabling people who historically were not equity investors—such as students—to begin owning and trading stocks.
