It won't surprise you to hear why Adobe is ramping things down: the internet has moved on. Shockwave use has "declined" as technologies like HTML5 and WebGL have taken over, the company said. It's betting that developers would rather move on to newer, truly universal formats if they're still committed to supporting their web apps.

You might not miss it too much on most websites, but it could still cause problems. Many older web games and media experiences were built around Shockwave, which enabled visually exciting web apps at a time when HTML wasn't up to snuff and powerful, consumer-friendly smartphones were just pipe dreams. When many of the developers ended support long ago, the death of Shockwave is likely to make those apps unusuable.
