The MySpace service was founded in August 2003 as a new initiative and 100% owned division of publicly traded internet company eUniverse (which later in mid-2004 changed its name to Intermix). eUniverse created and marketed the Myspace website, providing the division with a complete infrastructure of finance, human resources, technical expertise, bandwidth, and server capacity right out of the gate so the MySpace team wasn’t distracted with typical start-up issues. The project was overseen by Brad Greenspan (eUniverse's Founder, Chairman, CEO), who managed Chris DeWolfe (MySpace's current CEO), Josh Berman, Tom Anderson (MySpace's current president), and a team of programmers and resources provided by eUniverse.

The very first MySpace users were eUniverse employees, the company held contests to see who could sign-up the most users The company then used its resources to push MySpace to the masses. eUniverse used its 20 million users and e-mail subscribers to quickly breathe life into MySpace , and move it to the head of the pack of social networking websites. A key architect was tech expert Toan Nguyen who helped stabilize the Myspace platform when Brad Greenspan asked him to join the team.
