Today Oprah Winfrey signs off after 25 years as the queen of daytime talk. Oprah has built a multi-billion-dollar media empire. She’s one of only two African-Americans ever to grace the Forbes billionaire list – and the only black woman ever to do so.

So whether you’re a critic or a diehard fan, there’s no doubt that Oprah has had quite an impact – particularly on the African-American community. Joining us to reflect on Oprah’s legacy is Hilton Als, a staff writer for The New Yorker.
