Investopedia, a division of ValueClick, Inc. was founded in 1999 by Cory Wagner and Cory Janssen. Its original concept was based on building the most comprehensive financial dictionary online. Over time, the focus of the site expanded to building educational content and tools to help empower the individual investor.
In April 2007, the site was acquired by Forbes Digital, having recognized the pure potential of Investopedia. After three years of ownership which resulted in significant growth and expansion of the website, Forbes sold Investopedia to ValueClick in August 2010.
