Hardy is best known for his work in his multiple runs with World Wrestling Entertainment (WWE). He also worked for Total Nonstop Action Wrestling (TNA), Ring of Honor (ROH) and several companies on the independent circuit. Before gaining prominence in the WWE, Jeff, along with his real life brother Matt, ran and performed for the Organization of Modern Extreme Grappling Arts (OMEGA). The Hardy brothers worked as enhancement talents for the WWF from 1994, and were signed to full-time contracts in 1998. They gained notoriety in the tag team division, partly due to their participation in Tables, Ladders and Chairs matches. With the addition of Lita, the team became known as "Team Xtreme" and continued to rise in popularity. Alongside Matt, Jeff has held twelve world tag team championships between WWE, TNA and ROH.
