Steve Jobs disregarded that advice. In fact, one of his first acts as CEO was to stop licensing Mac OS to other hardware providers. The industry’s other article of faith was that companies needed to maximize market share by having a presence in every link of the computer chain, from servers to printers to PCs to laptops. Likewise, they needed to make PCs in all shapes and sizes for every possible user. But Jobs immediately killed the majority of Apple’s products, including most of its PC models, as well as all of its servers and printers and its Newton handheld computer.
