“In addition, like many companies, Sony worried about cannibalization. If it built a music player and service that made it easy for people to share digital songs, that might hurt sales of its record division. One of Jobs’s business rules was to never be afraid of cannibalizing yourself. “If you don’t cannibalize yourself, someone else will,” he said. So even though an iPhone might cannibalize sales of an iPod, or an iPad might cannibalize sales of a laptop, that did not deter him.”
