24 August 1995: Windows 95 launches with a Rolling Stones soundtrack

Microsoft launched Windows 95 with a huge marketing campaign built around the Start button and the Rolling Stones song Start Me Up. People lined up at midnight to buy an operating system. It introduced the Start menu and taskbar and made PCs friendlier for millions of new users. It also cemented Microsoft's dominance, which helped make it the most valuable company in the world by the end of the decade.

The lesson: Owning the platform everyone else builds on can produce extraordinary, long-lasting profits.

What it meant for investors

$1,000 in Microsoft at the start of 1995 → $160,000 today, vs $14,783 in the S&P 500.

We start the clock at the start of 1995, the year it happened. That is 160.0 times the money, and $145,217 more than a plain index fund made over the same years.

What Microsoft teaches: A great business bought at a silly price can still deliver a lost decade; Microsoft's profits grew for years while its 2000 valuation slowly deflated.
