Indians like medical school. Indians like practicing medicine. We've also established that Indians like watching any portrayal of themselves in the media. It would follow then logically that Indians like watching other Indians in television shows about medicine. The bad news is there aren't that many Indians in these shows. The good news is that Indians like pointing that out.
In shows such as ER, Grey's Anatomy, House, Chicago Hope, Scrubs, and St. Elsewhere Indian characters have been rarely seen. It's only recently that ER added an Indian cast member and Gray's Anatomy included an Indian dude in Meredith's long line of sexual sexploits (not even a doctor, or South Asian apparently since he's listed in the credits as Steve Murphy). Fortunately Heroes has Mohinder Suresh, but I think he may be one of those fake PhD doctors like Dr. Pepper or Martin Luther King.
With so many Indians in medical school, majoring in biology and going to Stanford it's only a matter of time before popular media begins to reflect the realities of the current medical field. However, I don't know how exciting an episode of Dr. Biswas HOUSE would really be:
Nevermind. That show would suck.
