After 24 years at CBS News, Harry Smith is saying goodbye to the network.

According to TV Guide, Smith is heading to rival broadcaster NBC to launch a new primetime newsmagazine with 'NBC Nightly News' anchor Brian Williams.

Smith began working at CBS in 1987, and most recently co-anchored 'The Early Show' and 'CBS This Morning.' He has also contributed to 'CBS Evening News' as a senior correspondent and substitute anchor.

In December, after CBS announced the changes to 'The Early Show' lineup, executive producer David Friedman said 'Early Show' newsreader Smith would "shift his focus to hard news with an expanded role as primary substitute anchor on 'The Evening News with Katie Couric,' 'Face the Nation' and 'Sunday Morning' while continuing to report major stories for all CBS News broadcasts."

Friedman said he decided to make such sweeping changes to the morning program after he "looked at many different aspects of the show and tried to figure out what needed to be changed," adding that "obviously if things were, quote unquote, working, we wouldn't make changes."
