Silverlight
.NET in the browser via plugin. Netflix used it; the web moved on anyway.

Silverlight failed because the web stopped tolerating plugins and Microsoft pivoted to Azure instead of fighting Apple. Teams bet on a runtime with an expiration date. The costly part was rewriting rich clients twice in one decade.
