Founded by former MySpace chairman Richard Rosenblatt, Demand has created a system through which writers and programmers are assigned stories or projects based on a software algorithm, which determines the interest of Web visitors and calculates potential revenues from the content. To date, it's struck deals to supply content to the Atlanta Journal-Constitution and Gannett's USA Today. People familiar with the company said it is expected to generate about $250m in revenue annually. Since 2006, the company has raised $355 million from such investors as Goldman Sachs, Oak Investment Partners, Spectrum Equity Investors and Generation Partners.
