How Black People are represented in Magazines , Adverts , and Films , and why is it such controversial Topic ?

In here you can see 3 different representations of Black women's in different magazines , if you notice they all contain the usual conventions of women , they are all looking directly to the camera to attract the audience , they have the male gaze as their hands and their body are positioned in a seductive way in order to attract the targeting audience .

However I noticed that they are given a more (white) , perspective as there hair is straightened and her faces contain  a light pointed to their faces to make them look more whiter , if you notice there is no actually Black women being showed  , on the other hand we could say that their representation is quite positive has they are only showing some parts of the body but is not to much .
