Media, overall, is quite diverse, perhaps even more so than population percentages alone would strictly indicate. That Hallmark might not reflect a great deal of diversity probably is attributed to them marketing to their niche audience, who seem to enjoy their rather traditional, squeaky clean and homogenized offerings. I find for the most part their programming is redundant, predictable, somewhat tedious and certainly overexposes the same group of actors, but so be it. Cable, the networks and other media providers offer so many options, some offering programming exclusive to certain ethnic groups where diversity is certainly not much of a factor, that there's really every opportunity to pick and choose programming that meets one's individual interests and preferences.
