NEW YORK -- CBS brought in a show doctor for Bryant Gumbel's newsmagazine, "Public Eye," while NBC hired Marcia Clark to provide legal commentary for its news programs.
Jonathan Klein, executive vice president of CBS News, was brought in Thursday to replace Michael Rubin, the original executive producer of "Public Eye." The show will be moved to Tuesday.
CBS won a bidding war this spring for Gumbel, the former "Today" show host, who set up "Public Eye" as a mixture of live interviews and taped segments.
Since its premiere, it has struggled in the ratings and taken some critical drubbings. It was rated No. 62 of 109 prime time programs last week by Nielsen Media Research.
"I don't think the show has felt as big or important as we would like it to be," said Klein.
Klein said the changes don't reflect a lack of confidence in Gumbel, who signed a contract that could be worth $5 million a year after leaving "Today."
Clark, the O.J. Simpson prosecutor, will provide commentary on legal cases for NBC and its cable sister MSNBC, and be an occasional guest host on CNBC prime time programs, the network said Thursday.
"Marcia is an accomplished lawyer and her legal mind will bring important insight to our coverage on both network and cable television," said David Corvo, vice president of NBC News.
