To contrast from Dr. Rey there are some Doctors who may not be household names like him, but they showcase their medicine via media outlets also.
The Discovery health channel has a new commercial advertising their new medical reality tv lineup; it features Dr. G-Medical Examiner, Dr. Jan Adams-Plastic Surgeon, Dr. Oz-Cardio and some other people I can't remember.
They have some good programs that don't make a mockery of "the art of medicine". This past weekend they had a Pathologist, GYN doc, and Oncologist talking about HPV, cervical cancer, the vaccine, diagnostic tests, treatments etc. (all interspersed with pathology animations, patient stories and laymen questions) on their Discovery channel CME program, which airs on Sundays.
Doctors are also used as consultants on ER, Grey's Anatomy, CSI, HBO and Court TV. Shoot, Dr. Baden-Pathologist (who has the Autopsy series on HBO) was just on the Montel Williams Show discussing a case he solved. Not a bad way to make a living while maintaining your reputation and dignity.
