A change of executive producers on “The Late Late Show With Craig Ferguson” puts two “Tonight Show” veterans in charge of the late-night CBS show produced by David Letterman’s Worldwide Pants.

Longtime Johnny Carson producer Peter Lassally, who will continue to hold the title of Worldwide’s senior VP for the West Coast, is the new “Late Late” executive producer and Gary Considine, who was “Tonight” executive producer from 1992 through 2002, has been named co-executive producer.

They succeed Todd Yasui (another “Tonight Show” veteran), whose contract was not renewed. Mr. Yasui was executive producer for Craig Kilborn, who left “Late Late” last summer.

Mr. Ferguson, a Scottish-born comedian-actor-writer-producer best known for his role as the off-center boss on “The Drew Carey Show,” was one of the early standouts in a long series of on-air auditions.

Since his debut as host in January, data from Nielsen Media Research shows Mr. Ferguson has attracted more viewers than Mr. Kilborn did, averaging 1.81 million viewers through this month, up 6 percent compared with Mr. Kilborn in the comparable time frame in 2004. “Late Late’s” following among adults 18 to 49 and adults 18 to 34 is down 5 percent and 6 percent, respectively, year to year.

“I believe Craig Ferguson has an unbelievably bright future in this business, and I am excited to continue playing a part in the great strides he and his show are making,” Mr. Lassally said in the announcement Thursday. “In six short months, Craig has already put his imprint on ‘Late Late Show,’ and I believe with the team we now have in place it will continue to develop around his unique comedy and intellect.”
