Racial diversity is slowly coming to American TV, according to a new report from a media watchdog group. Hispanics have made the greatest gains in recent years, with Hispanic characters being introduced in many mainstream shows, but Asian-Americans are still grossly underrepresented on U.S. screens. The coalition that issued the report singled out CBS’s new drama, Joan of Arcadia as being absurdly devoid of Asian-Americans, since it takes place in the heavily Asian town of Arcadia, California. Still, the coalition is no longer calling for the network boycotts it threatened a few years ago, and acknowledges that real progress is being made.
