The Washington Redskins-N.Y. Giants NFL game Sunday afternoon on Channel 9 averaged a 36.1 rating and a 62 percent audience share between 4 and 7 p.m... .

Each ratings point represents 17,491 TV homes ...

Michael Moore, who has been president and CEO of Channel 7 since February 1988, has submitted his resignation, effective at the end of the year ...

In a memo to the staff, Moore said that "in discussions with Marvin Shirley over the past several days, I have learned that he thinks it best that an experienced broadcaster lead the station in what we all know will be an increasingly challenging future" ...

Shirley is executive vice president of Allbritton Communications Co., in charge of the broadcast division -- and Moore's boss ...

"Accordingly, in a spirit of team play," Moore's memo continued, "I will submit my resignation effective December 31, 1990, and, in the interim, will assist in the search for the best possible general manager for this station. I expect to remain with Allbritton Communications Co., but do not know at present what my next assignment will be ...

"My role for the past three years has been primarily to oversee a critical transition period in the station's history" ...

Moore, 45, replaced Tom Cookerly, who had been president and GM of Seven for 16 years. In the nearly three years since his takeover, he has overseen the move of WJLA to posh headquarters on Tilden Street NW ...

But this past year has been a tough one for Moore. Ratings for the late-night local news bottomed out. The audience bonanza expected from the costly acquisition of the "Oprah Winfrey Show" for the key 4 p.m. timeslot never really developed, although the early-evening news shows remained competitive with WRC and WUSA ...

In late spring, Moore lost the services of executive vice president John Long -- who had considerable TV station management experience -- when he resigned to form his own consulting firm ...

The bottom fell out in July after months of budget reviews. Moore -- at Shirley's insistence -- pushed through severe cuts at the ABC affiliate that resulted in the departure of at least 22 employees, about half from the news unit, the axing of a 5:30 morning news show, and a rearrangement of all major anchor assignments ...

As plans for the 10 percent staff reduction firmed up, news director Bob Reichblum resigned over the expected impact on his unit. And it was only last month that Gary Wordlaw, the city's first black news director, was brought in from Baltimore to replace Reichblum ...

Moore's decision to step down was not unexpected. Moore has never made a secret of his lack of broadcasting experience. He has been associated with banker-investor Joe Allbritton since 1977, when he joined the former's Houston bank staff as controller ...

He later had key financial roles for Allbritton enterprises in Great Britain and Luxembourg. He also served as president and CEO of the Trenton (N.J.) Times Corp. as well as head of Allbritton's group of five daily newspapers ...

But insiders say that several months ago Shirley had begun openly making inquiries about a possible replacement for Moore ...

Yesterday, the WJLA president declined to elaborate on his memo. Shirley, attending a business meeting in Arkansas, was unavailable for comment ...

Meanwhile, in Miami, it was announced that Reichblum has been named news director of WPLG, the 16th-largest TV market's number one station -- and a Post-Newsweek station to boot -- effective immediately ...

Reichblum joined WJLA from Post-Newsweek's WDIV in Detroit, where he had been executive news producer ...

He replaces Mike Sechrist, who has moved to KDFW, the CBS affiliate in Dallas, owned by the Times Mirror Co. ...

In Other NewsABC News has put plans for a five-hour weeknight, overnight news service way on a back burner ...

Nobody will come right out and say it but the chances are very good that it's dead as a dodo -- at least until such time as the network affiliates, who are feeling their own budget pinches these days, pitch in with programming costs if they really want overnight news ...

But as late as last Thursday, the ABC News overnight-news planning staff had been assembled in New York to discuss details of a probable February launch ...

Instead, after an all-day look at the costs, word went out of its trip to the deep freeze ...

The action came as Capital Cities/ABC Inc. management last week notified division chiefs of a hiring freeze. The overnight news service would have probably resulted in at least 40 hires, so it was a natural to be the first project to hit the shelf ...

There are reports that ABC News plans to close several domestic bureaus, but whether that will result in a net loss of employees has not been determined ...

The number one network in news, however, still expects to go ahead with plans to boost overseas bureaus in Berlin, Johannesburg and other locations, as previously announced ...

At NBC, the News division has already announced 25 upcoming layoffs, but those will be offset by hiring for several primetime programs being developed, according to insiders ...

The costs of covering the Persian Gulf crisis and an industry-wide decline in advertising revenues are behind the cost-cutting measures. ABC News, which had expected to make at least $75 million this year, reportedly already has cut its estimate to the neighborhood of $50 million ...

The loss of the overnight news project will be felt mostly at the Washington bureau of ABC News ...

Robert Wheelock has been named senior producer of NBC News's "Today" show. He replaces Jacoba Atlas, who has relocated to L.A. to establish a documentary programming unit for Gary David Goldberg's UBU Productions ...

Wheelock most recently was a field producer for "Today," and produced Bryant Gumbel's recent trips to Saudi Arabia and Berlin ...

Also at NBC News, Alan Abelson, a contributor to "NBC News at Sunrise," left the show Friday, apparently over a salary dispute. The network did not renew Abelson's contract. He is the editor of Barron's magazine ...

The Senate has confirmed Sharon Percy Rockefeller to the board of directors of the Corporation for Public Broadcasting ...

It will be the third term on the CPB board for the president and CEO of WETA here ...

CBS is planning a memorial service for Douglas Edwards, who died Saturday of cancer at his Florida home. He was 73 and had retired from the network in April 1988, after 46 years ...

Funeral services will be tomorrow at 3 p.m. at the Church of the Palms in Sarasota. In lieu of flowers, the family has requested that donations be made to the Hospice of Southwest Florida, 6055 Rand Blvd., Sarasota, Fla. 34238 ...

Mr. Edwards launched the first CBS nightly broadcast, "Douglas Edwards With the News," in August 1948. His evenhanded news sense set a standard that is sadly out of vogue today in the industry ...

But his peers at CBS News remembered. Charles Kuralt called Mr. Edwards "an old-fashioned journalist of the best kind -- always diligent and always fair, very accomplished as a writer and editor, and a calm presence before the camera. He was generous in giving credit to those who worked with him. He helped establish the credibility of news on the air. Viewers found him trustworthy; they were correct in their judgment of him" ...

Channel 26 announced yesterday that it will rebroadcast the historic 90-minute "Bernstein in East Berlin" concert on Sunday, Nov. 11, at 4:30 p.m. ...

The Christmas Day concert last year, marking the end of the Berlin Wall, featured a performance of Beethoven's Ninth Symphony ...

Mr. Bernstein died of a heart attack on Sunday in his New York apartment at the age of 72 ...

"Good Morning America" anchor Charlie Gibson flies to the West Coast Thursday to conduct an interview with former president Ronald Reagan to be aired over five mornings the week of Nov. 5, in conjunction with the publication of Reagan's autobiography ...

And finally, for you "Twin Peaks" freaks, we should report that Saturday's episode of the ABC series managed a 9.9 rating and an 18 share in Nielsen's 24 major overnight markets ...

Each ratings point represents (are you ready for this?) 440,292 TV households ...
