Eric Blossom is the founder of the GNU Radio project. GNU Radio is a free software toolkit for building software-defined radio and signal processing systems. His intention has been to build decentralized communication, moving away from infrastructure-based systems. One-way channels provided by broadcast radio and TV are heavily regulated, so there is a need for strategies that free content from being controlled by a small handful of powerful organizations, helping to liberate the user's interests rather than the operators'.

Prior to his involvement with software radio^[when?], Blossom worked in the secure phone business, becoming the co-founder and CTO of Starium Ltd., where he oversaw the design and development of a line of cryptographic equipment for the commercial marketplace. He is also the founder of an international consulting company called Blossom Research. Blossom practices yoga and jujitsu.
