Subversion (SVN)
Centralized version control that replaced CVS for enterprises — then git ate the default.
Subversion faded because distributed workflows, cheap branching, and GitHub gravity made central servers feel like a tax. It stuck in regulated shops with slow migrations. The idea of atomic commits stuck; the client-server default did not.

Context
The browser ate the desktop
The web became the default delivery surface. LAMP and Rails made shipping cheap; Ajax made pages feel like apps; SOAP/SOA tried to enterprise-ify the wire. REST won by being debuggable with curl. This decade invented the modern product cadence — and the habit of treating every new framework as destiny.
