IBM invented the personal computer. Then spent a decade methodically dismantling everything they built. This is the final chapter.

The OS/2 era. The Microsoft divorce. The slow retreat from a market IBM created from scratch — and the Lenovo deal that made it all official.

This is Part 4 of the IBM saga — the encore performance nobody asked for. We dig into how IBM tried to claw back control of the PC market with OS/2, why their partnership with Microsoft collapsed into one of the biggest tech company failures in history, and how the world's most iconic computer brand quietly handed its entire PC division to Lenovo for $1.75 billion.

If you thought the IBM story was about one catastrophic mistake — it wasn't. It was a subscription service of bad decisions. And this is the final invoice.
