Diane Sawyer and Jaycee Dugard Diane Sawyer and Jaycee Dugard

Some 14.78 million people watched Diane Sawyer's Sunday interview with Jaycee Dugard, who was kidnapped, raped and held prisoner for 18 years, in a special two-hour edition of Primetime — the biggest summer viewership for a newsmagazine in seven years.

The California woman's story is a compellingly harrowing tale: Just 11 when she was taken by Phillip and Nancy Garrido, she repeatedly was abused and gave birth to two children as a result of rape. Now 31, she has written a memoir titled A Stolen Life that's being published Tuesday by Simon & Schuster. (The couple who abducted her were recently sentenced to life in prison.)

Jaycee Dugard: I didn't know I was in labor

According to overnight Nielsen estimates, viewership for the special more than tripled that of two reruns on ABC a week earlier. It was the most-watched summertime newsmagazine since a 2004 edition of 60 Minutes — and it was the most-watched non-sports Sunday prime-time program on ABC since February's Oscar telecast, nabbing a 3.7 rating among 18-to-49-year-olds.

ABC announced Monday that it will rerun the interview on Saturday at 9/8c.

Big Brother shake-up: Evel Dick Donato leaves the house

Meantime, the first Sunday outing of Big Brother's 13th season on CBS grabbed 7.16 million in the 8/7c time slot against reruns, scoring a 2.5 demo ratings — its best first Sunday ever.

And The Curse of Seinfeld apparently is taking hold again as Jerry Seinfeld's The Marriage Ref  managed a meager 2.04 million viewers (and series-low 0.8 demo rating) on NBC to finish last in prime time's final hour. It was down 33 percent from last week.
