Wikipedia
Blockbusting was a business process of U.S. real estate agents and building developers to convince white property owners to sell their house at low prices, which they did by promoting fear in those house owners that racial minorities would soon be moving into the neighborhood. The agents then sold those same houses at much higher prices to black families desperate to escape the overcrowded ghettos. Blockbusting became possible after the legislative and judicial dismantling of legally protected racially segregated real estate practices after World War II. By the 1980s it largely disappeared as a business practice, after changes in law and the real estate market. After the millennium claims were made that it was again being practiced in New York State and New Jersey on behalf of orthodox Jews.
