Racejacking 

The practice of converting a long lasting popular white fictional character into a black one to appease political correctness and cries for "diversity".

Rather than create a popular fictional character with longevity it seems that it's easier to steal an established white character through racejacking.

So now marvel comics is making spiderman black. Now spiderman joins Nick Fury, The kingpin, James West, Green lantern and other victims of racejacking.
