NBC

TV networks officially reveal fall schedules next week, but word has already spread on some new shows and cancellations. NPR TV Critic Eric Deggans says early trends include more diversity, big names.

Andrew Lack held top roles at NBC from 1993 to 2001. He is returning as chairman of NBC News in the wake of Brian Williams' suspension as chief anchor.

The anchor, who apologized for misremembering that a helicopter he was traveling during the 2003 invasion of Iraq had been fired on, said he would return to hosting the Nightly News "in a few days."

The Nightly News anchor apologized this week for claims he was on a helicopter that came under fire in Iraq in 2003. Doubts have also been raised about his reporting during Hurricane Katrina.

The NBC Nightly News anchor and his network have for years claimed he was aboard the chopper that was hit and forced down by enemy fire in 2003. Williams now says he made a mistake.

NBC Chairman Bob Greenblatt said it was "safe to say" there won't be any future projects with the comedian who starred in the network's iconic The Cosby Show.
