TV adverts in the UK became flooded with black actors since about 1-2 years ago. The ratio of black to white in adverts appears to be about 50:50. The actual percentage of black people in the UK population is 3%.
Half of the black population of the UK live in London, the other half live in 5 major cities.
Especially odd is when our adverts show black actors involved in pursuits like surfing, skiing, hiking, mountain climbing, sailing, camping etc.. Actually meeting black people involved in such activities here is about as rare as finding hens' teeth.
I suppose this comes from insecure commercial clients wishing to demonstrate their open-mindedness and respect for all races. Which is odd because that's something nobody ever accused them of.
