James L. Dolan (born 1956) is Chairman of the Board of Cablevision Systems Incorporated -- parent company of the Madison Square Garden corporation, in New York City. He has had numerous feuds with his father, Charles Dolan, regarding the ownership and financial stability of Cablevision. James Dolan is well-known for his stewardship of the professional sports teams that Madison Square Garden (MSG) owns: the National Basketball Association's New York Knicks, the National Hockey League's New York Rangers, and the WNBA's New York Liberty. Dolan's results as a sports franchise owner have been financial success, mixed with competitive failure -- aside from a few good seasons (notably 1999, when the Knicks made it to the NBA Finals).
Dolan also purchased The Wiz, a faltering New York City-based electronics store chain. Ultimately, he failed to sustain it, despite heavily cross-promoting it with Cablevision's popular Optimum Online service.
Dolan performs blues-inspired rock as the singer for JD and the Straight Shot.
