Black Santa

As the holiday season rolls in, and certainly not fast enough, I was thinking about and hoping he comes to my house. But how come there has never been a black representation of Santa? I'm sure someone has used a black male as Santa but certainly it has never come anywhere near catching on in the mainstream. I guess I want to ask the basic question of why? Santa is completely socially created so why have we excluded all minorities from this? I understand there is a story behind St. Nick but we could have at least altered it to make it more inclusive. We can have flying reindeers but not an African-American Santa?
