The Tennis Channel, a 24-hour digital channel scheduled to launch in Q1, has established an online petition site to help enthusiasts tell their cable providers they want the new channel. The online
petition site, officially launched Dec. 17, 2002, has already garnered the support of Hollywood celebrities such as Dule Hill ("West Wing"), Camryn Manheim ("The Practice"), Wendie Malick ("Just Shoot
Me") and Dr. Phil, as well as Pete Sampras, Andre Agassi and Brad Gilbert.
