KTLA has confirmed that program director Mark Sonnenberg will take over Monday as exec producer of the “KTLA Morning News” from Joel Tator, who is headed to Burbank to exec produce Tom Snyder’s new CNBC cable show.Sonnenberg, who will continue in the program director post he has held since June 1988, will also helm a new 9-10 a.m. locally produced morning show slated to debut in the next few months. “Morning News” producer Ray Brune, meanwhile, has been elevated to supervising producer. He has been with the show since its inception in July 1991 . Tator, who becomes a “Morning News” consultant, joined the popular program as E.P. in November 1991. He was brought in as an exec consultant to the newscast shortly after it began, helping to craft a format that leans heavily on lighter elements. KTLA’s ayem news show quickly jumped to No. 1 in last February’s ratings sweeps, and has been at or near the top of the ratings ever since. Tator chose to leave the morning show because it would be too difficult to handle both the early morning chores and the Snyder show, which will air at 7 p.m. Eastern time. Over the course of his 30-plus year career, Tator served stints as a producer and director of Snyder’s old NBC “Tomorrow” show.
