Ellis, we watch many of the same NBC shows. Your list includes all of those I watch, and some I don’t.
According to the CIA World Factbook, U.S. population is 12.9% black and 4.2% asian. I would say that it is fair to assume that those populations are mostly concentrated in major metropolitan areas, such as San Francisco (Journeyman), Chicago (ER), New York (Heroes, 30 Rock), etc.
I do mean “awfully white”, because when dealing with urban settings, many of the ratios of white / non-white change dramatically. All those shows have token diversity. I haven’t watched ER in ages, but the last I checked, they’re racial breakdown did not match any city hospital I’ve ever been in. I pointed out that Chuck has an abundance of hot Asian women because it stands out and the writer or producer probably has a thing for them.
The Office and My Name is Earl are two shows where, IMO, it makes sense to have a token figure (btw, Office has two - don’t forget Darryl). 30 Rock somewhat makes sense, as long as they don’t venture outside of the corporate/stage area. Scrubs also makes sense, somewhat, however, it could certainly use a lot more diversity outside of the leads and secondaries. We could probably count the number of non-white patients and background characters they’ve had on our fingers and toes.
Part of the problem is the pool of working actors wherever they are filming. They purposely hire token leads, but when they do a cattle call for crowd scenes, I’m guessing they are being sent an all (or mostly) white crew unless otherwise specified. I picked on Chuck because even the store scenes are melanin-deprived. I’ve been in “Buy More” in mostly white suburbs, and I would expect much more of a rainbow throughout the store.
Another part of the problem is the appeal to demographics. According to the Factbook, 81.7% of the country is white, and there is still a large swath of non-urban whites who simply do not relate to minority characters, especially if they “act minority”. It is what it is. Personally, I’d like to see a show with a cast that reflects my own Queens block…we have representatives from at least 9 countries throughout Europe, Asia, and Latin America - either born outside the US or first generation.
