Open Source: From Community to Commercialization - Peter Levine, A16Z

The open source software (OSS) movement has created some of our most important and widely used technologies, including operating systems, web browsers, and databases. Our world would not function, or at least not function as well, without open source software.

*While open source has delivered amazing technological innovation, commercial innovation – most recently and notably the rise of software-as-a-service – has been just as vital to the success of the movement. And since open source is by definition software that is free for anyone to use, modify, and distribute, open source businesses have required different models and a different go to market than other kinds of software companies.
