In other words, post-colonialism is related to looking at the effects of the European nations in other countries that were colonized such as Africa. When European nations were the world powers around the 15th to 20th century, they started to "colonize" other countries for goods and raw materials. They would use the country and it's people to harvest supplies such as silk, cotton, and spices and bring them back to the mother country to profit. Consequently, this put the European countries at a much higher ranking than those not of the white race. Born from ethnocentric views, colonies were expected to familiarize themselves and respect the culture of Europeons, abandoning their own foolish and primitive ways. How were the colonies then affected? Studying the effects born from colonialism is post-colonialism...
Moving on comtemporary media:
Has anyone heard of the brand "United Colors of Benetton"? It's a Italian clothing brand but they come up with the most controversial ads EVER.
Here's one example:
Titled, "Angel and Devil",
Released in September of 1991, the company aimed to spark conversations about the stereotypical "white is good, black is bad" image by releasing the above ad of a white girl being depicted as an angel and a black child potrayed as a devil. The company is quoted to say that they aimed to "feature images from the real world which have some social and universal relevance, in order to break through the barrier of indifference which often surrounds these issues". In reality, they only caused an upheaval of controversy and summoned anger from the public. However, if the underlying purpose was to get public attention, they certainly achieved it.
