DOCUMENTARY SERIES PREMIERE: CNN’s latest documentary series about a specific decade, The Nineties, premieres tonight, with an expanded two-hour opener looking at, as usual, television. This time it’s called “The One About TV,” which is a clear nod to NBC’s Friends, one of the clear hits to emerge from that decade. Others include Seinfeld, NYPD Blue, The West Wing, The Sopranos, ER, The Larry Sanders Show, and the program charts the clear emergence of cable TV as a vital source of new quality television. Fair warning: I’m in here somewhere, as a talking head – but I keep doing these CNN episodes about TV because the producers keep doing them so well. I recommend The Nineties not because of my tangential involvement, but in spite of it. So watch The Nineties, and see, all over again, Ellen come out, Tony Soprano strangle a guy, and O.J. make a break for it.
