The major drawback of NBC's highest-rated programming this year -- the Summer Olympics -- is that there appeared to be little-to-no chance of repeating it, analysts observed at the time. But they apparently did not take into account the opening ceremony which set audience records when it aired from Beijing in August. On Thursday NBC announced that it will air an edited version of the ceremoy ("TV Event of the Year") as a two-hour special beginning at 8 00 p.m. on Saturday, December 27, hosted by Bob Costas and Matt Lauer. The original telecast was directed by famed Chinese filmmaker Zhang Yimou. The special will also include the Games' "greatest moments," including, of course, the performance of Michael Phelps in the swimming competition.
