The growth of Unity into the most popular game engine in the world

Recently Unity made the headlines for some sketchy changes to their pricing policies. They've since walked back on those changes. Being a game developer, I took the opportunity to look into Unity, the company, and understand more of its history.

I compiled a timeline of their headcount since 2004 based on old articles, and more recently their SEC filings, and used Yahoo Finance for the "U" ticker stock value.
