For 18 years, Jaycee Dugard was held captive after having been kidnapped at a bus stop within sight of her home in California when she was 11 years old. She was rescued in August 2009 along with two daughters fathered by her abductor.

She sat with her mother, Terry Probyn, by her side to talk with Diane Sawyer on a 'A Special Edition of Primetime' (Sun., 9PM ET on ABC).

The women recalled the emotional moment over the phone when the authorities called Probyn at work to tell her that Dugard had been recovered.

Probyn said her response was that it was "absolutely unbelievable. And then it was disbelief. I said, 'No, you're joking. Don't do this to me. This is not funny.'"

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."

Jaycee Dugard, the California woman who was abducted as a child and held in captivity for 18 years, will break her silence about the ordeal in an exclusive TV interview with Diane Sawyer.

Multiple news organizations had been trying to secure an interview with Dugard and, according to 'The New York Times,' ABC signed a deal earlier this week.

A spokesman for the network said that "Dugard will be asked about the extraordinary and heartbreaking story of her captivity [and] her reunion with her family," adding that the interview will air shortly before her memoir, 'A Stolen Life,' is published on July 12.

However, exact details of when the interview will air, and on which show(s), have not yet been announced.
