A Brief History

● 2009 - Originally written by Ryan Dahl, sponsored by Joyent

● 2010 - Node Package Manager (NPM) introduced

● 2011 - MicroSoft and Joyent release native windows support

● 2014 - io.js fork created by the community due to differences in governance

● 2015 - Neutral Node.js Foundation created as part of the Linux Foundation

● 2015 - Red Hat joins Node.js Foundation as a Platinum Member
