Next weekend, CNN premieres The Nineties, the latest entry in its series of miniseries documentaries exploring specific decades. That series began with The Sixties, and tonight, as a form of catch-up, CNN repeats The Seventies in a marathon showing beginning at 10 p.m. ET tonight, including an episode devoted to such 1970s TV landmarks as Charlie’s Angels. That is, if breaking news doesn’t obliterate that plan, which has been happening a lot lately with CNN’s specials. Oh – and I should say that, if you watch the episodes devoted to television, I’ll be in there somewhere, whether you’re watching The Sixties, The Seventies, The Eighties, or, next weekend, The Nineties.
