Consider the plight of the televised health professional.

There was a time when all it took was the right couple of letters in front of your name and the divine blessing of Oprah Winfrey, daytime TV’s resplendent queen, and you could find yourself hosting a hit television show. With just those advantages secured, both Dr. Mehmet Oz and Dr. Phil McGraw landed themselves eponymous programs with which to dole out their wisdom to audiences at home.

Alas, the bloom has begun to come quite noticeably off those particular roses. And it may be time to ponder whether or not these shows, each proudly affixed with “Dr.” right in their titles, have exploited their stars’ professional credentials well past their sell-by dates.
