Blockbusting
From Wikinvestor
Blockbusting was a practice used by real estate agents and developers in the United States to encourage white property owners to sell their homes by giving the impression that minority groups (such as African Americans) were moving into their previously racially segregated neighborhood.[1] Blockbusting became possible following the dismantling of legal protection of segregated real estate practices following World War II, but by the 1980s it disappeared as a result of changes in law and the real estate market.[2]
