I Spy was a true breakthrough moment in TV history. A black actor on equal billing with his white counterpart and the series lasted three seasons. That was as woke as 1965 could get.
Explicitly, right from the first episode.
The other show that was similarly progressive was Danger Man, though a UK production. Some unfortunate yellow and brown face, but excellent Black casting and, far rarer for the time, frequently starring women of competence and independence.
