NPR's Leroy Sievers, the former Nightline executive producer whose battle with cancer was documented on his NPR blog, died last night.

Sievers was one of Ted Koppel's executive producers at Nightline, and later moved with Koppel to the Discovery Channel where he oversaw the 2007 documentary "Our Children's Children's War," which aired in March 2007. Sievers, along with Lance Armstrong and Elizabeth Edwards, was prominently featured in Koppel's "Living with Cancer" broadcast, which aired on Discovery in May, 2007.

Sievers was first diagnosed with colon cancer in 2006. By June of this year it had spread to his brain, shoulder blades, liver, pelvis and lungs.

Merv Griffin, who was producing up until his final weeks of life, died today of prostate cancer. Griffin was one of Hollywood's most boundless executives. He began his career as a singer, hosted "The Merv Griffin Show" for more than 20 years, created the hit game shows Wheel Of Fortune and Jeopardy! and, later in life, became a real estate magnate.

"My father was a visionary," Griffin's son, Tony Griffin, said in a statement issued today. "He loved business and continued his many projects and holdings even while hospitalized." Griffin's latest project Merv Griffin's Crosswords premieres in syndication next month.

Griffin was a guest on FOX & Friends just last month. In what would be his last interview, Brian Kilmeade asked Griffin about his legacy and how his television show impacted politics: "The Kennedy White House would call my producer," Griffin said, "so they became aware of how valuable the talk shows were to a candidate." "The 23 years I did my show, nobody knew what my political affiliations were." Merv Griffin was 82.

Legendary Los Angeles anchorman Hal Fishman died today. Fishman, who would have turned 76 on August 26, suffered from colon and liver cancer. Fishman had anchored KTLA's 10pm newscast since 1975. He joined the station in 1965, and contributed to the station's Peabody Award-winning coverage of the Watts riots that year.

KTLA's newsroom was named in Fishman's honor in 2000.

>From an LA emailer: "I can't think of another local news anchor anywhere I've lived who has had such a strong connection to his audience and city. Watching him when I go home is like catching up with an old friend."
