Of Black America was a series of seven one-hour documentaries presented by CBS News in the summer of 1968, at the end of the Civil Rights Movement and during a time of racial unrest (Martin Luther King had been assassinated that spring and riots in many cities had followed). The groundbreaking series explored various aspects of the history and current state of African-American community. The executive producer was Perry Wolff, and the series was sponsored by the Xerox Corporation.
The series was presented in prime time at 10:00 PM, on Tuesdays (a slot then usually reserved for CBS Reports documentaries and news shows), except for the last episode which aired on a Monday.
The first installment (“Black History: Lost, Stolen, Strayed”) won an Emmy Award and a Writers Guild of America Award for Andy Rooney. –Wikipedia
