Investopedia 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.

The site attracts millions of visitors per month seeking to improve their financial understanding. Investopedia offers an abundance of financial content, from articles, dictionary terms, tutorials and video, to frequently asked questions and exam prep quizzes. Notable is Investopedia's Stock Simulator and FXtrader, where users can register for free and practice their investing skills with $100,000 in virtual cash in either the stock market or fast paced foreign exchange market.
