Announced October 28, 2018 and closed July 9, 2019, IBM's purchase of Red Hat was the largest software acquisition in history at the time — and a direct bet on hybrid cloud built around Linux and open source.
Launched January 6, 2011 with over 1,000 apps, the Mac App Store brought one-click purchase, download, and install to the Mac — and logged a million downloads within its first 24 hours.
Released July 29, 2015 as a free upgrade for Windows 7 and 8.1 users, Windows 10 reached over 75 million devices within a month — a deliberate bet on rapid adoption over per-copy revenue.

On June 29, 1994, a Usenet post to comp.os.msdos.apps proposing a public-domain DOS kicked off what would be renamed Free-DOS weeks later — a direct response to Microsoft's plans to fold MS-DOS into Windows 95.
Released December 17, 2003, the 2.6 series brought in-kernel preemption, NPTL threading, SELinux, and support for far larger process/user counts — the foundation the kernel built the next two decades on.

Released to manufacturing July 22, 2009 and to the public October 22, 2009, Windows 7 refined Vista's foundations into a release widely regarded as one of Microsoft's most successful, eventually selling over 630 million copies.
