CNN did this the other night and is doing it again tonight: repeating installments of its marathon documentary series, The Seventies, in preparation for this weekend’s unveiling of its newest entry in the series, The Nineties. I appear in the episode devoted to television, but given recent headlines, I’d recommend paying even closer attention to the episode about Watergate. CNN, by rebroadcasting The Seventies, is repeating history, true, but these days, history also seems to be repeating itself.
