For the first 45 years after Intel’s founding, from its first CEO Robert Noyce to its fifth, Paul Otellini, the company focused on perfecting the IDM (integrated device manufacturing) model. The “Intel Inside” campaign became a global success, cementing Intel’s position at the top of the semiconductor industry. It wasn’t until 2013 when Brian Krzanich became Intel’s sixth CEO that the company made its first tentative steps into foundry services.
