Premise: One of the medium's most beloved, sharply written and performed sitcoms, about the newswoman who could turn the world on with her smile. A winner of nearly 30 Emmys over its seven years, it consistently produced witty, sophisticated episodes, including the celebrated `Chuckles Bites the Dust,' which was No. 1 in TV Guide's ranking of the `100 Greatest Episodes of All Time.' Members of the extraordinary ensemble cast moved on to three spin-off series: `Lou Grant,' `Phyllis' and `Rhoda.'
