Ethnicity and television advertisements

 Last night while watching the advertisements during the half-time break in Sky's football coverage I noted how things have changed in the last year.  A year ago the non-white faces in advertisement probably represented the population as a whole.  Now we rarely see an advertisement without a black face in it. Mixed race couples abound as do same sex couples but that's another story.  I'm not saying we should only have white faces in advertisements but surely this is too much.  I remember how long it took to change the way women were portrayed in advertisements, more than a year!  Today we have a total dominance of one type of person and I for one would like to stop it and show advertisements which are representative of the whole population.  I live a few miles outside Manchester, a so-called melting pot of different races but walk around the area I live and a black face is a rare sight we have Chinese and Indian locals.  Let's get some sense of proportion about how we show our citizens.  Why do we feel the need to appease the black minority in the UK so much so much so that I'm beginning to feel like an outsider in my own country?
