International Business Machines History & Founding Timeline

IBM's 1981 decision to build the PC on an open architecture using Microsoft DOS and Intel processors — made to accelerate PC market development — created the conditions for the clone industry that commoditized IBM's PC hardware advantage within a decade, ultimately forcing IBM to exit the PC business entirely and contributing to the financial crisis of the early 1990s that nearly destroyed the company.

IBM was a decade late in building hyperscale public cloud infrastructure, allowing AWS (2006), Microsoft Azure (2010), and Google Cloud (2011) to establish dominant market positions before IBM SoftLayer and IBM Cloud could achieve competitive scale — forcing IBM to reframe its cloud strategy around hybrid cloud positioning rather than competing directly for public cloud workloads, a strategic retreat dressed as strategic differentiation.

IBM's aggressive marketing of Watson as an AI platform across healthcare, legal, finance, and general enterprise applications in the 2013 to 2018 period — including the controversial Watson Health division that was eventually sold in 2022 — overpromised AI capabilities that the technology of the period could not deliver, creating a reputational credibility gap that IBM's subsequent watsonx rebranding and repositioning has had to overcome.

IBM maintained the managed infrastructure services business (eventually spun off as Kyndryl) as part of its core reporting structure for too long, allowing the segment's low margins, slow growth, and eventual structural decline to dilute IBM's overall financial performance and cloud its strategic narrative with investors who struggled to separate the genuinely valuable software and consulting businesses from the commoditizing infrastructure services revenue.
