Faces to Watch in ’92 : These are the people Calendar’s critics and writers think you’ll be hearing about in 1992. In some cases, they’re familiar people who will experience a transitional year. Some are newcomers who could have a breakthrough year. : JEFF ZUCKER

Katie Couric started it, calling Jeff Zucker “Miles,” as in Miles Silverberg, the young producer on “Murphy Brown.” But the nickname that’s stuck is “Doogie,” as in Doogie Howser, ABC’s teen-aged medical prodigy. “Doogie” is catchier, but “Miles” is a better match. Like Silverberg, Zucker is an intense Harvard graduate who’s just gotten--at 26--one of the biggest jobs in network news: executive producer of NBC’s “Today” show. Zucker began his career in TV five years ago. An editor of the Harvard Crimson, he had been planning to go to law school until a friend at NBC Sports got him a job as researcher for the 1988 Olympics. Once he saw the inside of a TV control room, he was hooked. Zucker worked with Bryant Gumbel on the Olympics and then joined “Today” as a segment producer. He became Couric’s producer in 1990 and the show’s supervising producer for the last year. Zucker’s ability to work well with Gumbel is considered one of his strengths. With Couric and Gumbel, “Today” is finally recovering from the Jane Pauley/Deborah Norville debacle and moving ahead against top-rated “Good Morning America” on ABC. Although he’s a card-carrying member of the MTV generation, one of the changes Zucker is bringing to “Today” is emphasizing hard-news coverage and extending segments when they get interesting. “I hate the rigidity of the morning shows--4 1/2 minutes and it’s, ‘Well, Mr. Gorbachev, we’re out of time.’ ”
