The Canadian writer Malcolm Gladwell has a podcast called "Revisionist History" http://revisionisthistory.com/ in which he drills into particular episodes of US history.

I find it interesting, even though I don't have the academic historical chops to independently assess its accuracy.

Example: In the episode called Miss Buchanan's Period of Adjustment, Gladwell explains that Brown v. Topeka Board of Education (the famous school integration case) had a severe consequence. It caused a large fraction of African American schoolteachers and educators to be thrown out of work. He points out that teaching was a major source of 1930s-1950s knowledge-work employment for African Americans was teaching in segregated schools. Quite a few Euro-American school boards obeyed the ruling admitting African American students, but did not employ the teachers from thew schools they left.
