The staff cutbacks, first announced by Channel 7 in July, have caught up with a couple of on-air regulars ...

Latest to get walking papers are movie and theater critic Henry Tenenbaum, whose last appearance will be Friday, Sept. 14 ...

And very early morning weathercaster Steve Udelson, who has been told his contract won't be renewed when it comes up in mid-December ...

Tenenbaum started at Channel 9 in this market in 1974 and also worked for WRC for six years during the 1980s, before joining WJLA in 1987. Until August of this year, he has also been doing a syndicated movie review for Post-Newsweek Stations ...

When Post-Newsweek canceled the reviews (they discovered local stations prefer, when possible, to do their own) Tenenbaum was hopeful he could work out a similar deal with WJLA. But the thinned-out management ranks at Seven decided, with so much else on their plates right now, they couldn't go into the syndication business in the immediate future ...

Tenenbaum was notified last week his contract was not going to be renewed. The reviewer said yesterday he's working on a couple of deals and is hopeful he can remain in the Washington area. Sources suggest a couple of networks may be dickering for his services ...

Udelson, who came to WJLA two years ago from WLVI in Boston, has been weathercaster on the 5:30 a.m. and 6:30 a.m. local news. As part of the "streamlining," as WJLA management prefers to call the process, announced in July, Seven is canceling the 5:30 half-hour as of Oct. 1 and a reformatted 6:30 news will probably eventually eliminate a regular weathercaster ...

In July, after losing top executive John Long, Seven management didn't protest when news director Bob Reichblum resigned, and shortly thereafter it eliminated some 20 jobs, including about 10 in its news unit, effective at the end of this month. There's a chance the streamlining could affect a few more at the station before the year is out ...

WJLA, by the way, reports that its one-hour mayoral forum Tuesday averaged a 6.2 rating and a 12 share at 10 p.m. Renee Poussaint anchored, and Susan King and Del Walters tossed out the questions to the seven candidates ...

And -- this may not be exactly the right spot for the announcement -- Seven will air that critically acclaimed "20/20" special edition on depression this Friday night starting at 1 a.m. ...

WJLA preempted the program last Friday in favor of the Redskins game ...

In Other NewsThe Battle of the Anchors is moving to another venue this weekend ...

NBC News announced yesterday that Tom Brokaw, who has been mostly desk-bound in New York since the Persian Gulf crisis broke out in early August (he did spend a week in the Middle East), will be reporting from Moscow on Friday and from Helsinki, site of the Bush-Gorbachev summit, on Saturday and Sunday ...

He leaves today. Jane Pauley will substitute tonight on "Nightly News," while Faith Daniels will anchor from New York on Friday ...

With Brokaw as anchor, NBC will devote 4 1/2 hours to live coverage from Helsinki on Sunday, starting at 8 a.m., which, if current plans hold up, will conclude with a special "Meet the Press" from Finland at noon. The special will preempt the regular "Sunday Today" ...

White House correspondent John Cochran and State Department correspondent John Dancy will also be in Helsinki ...

With the White House and congressional budgeteers due to meet at Andrews Air Force Base this weekend too, it could be a busy news weekend ...

CBS News anchor Dan Rather, who has dibs on the Persian Gulf story so far, will finally depart Saudi Arabia for Helsinki to report Saturday and Sunday on the summit. He will be joined by White House correspondent Lesley Stahl ...

Rather, who has been in the Middle East from the start of the crisis, reportedly will finally return home to New York at the conclusion of the summit -- barring another serious turn of events in the gulf, of course ...

CBS's "60 Minutes," which has energized its usual summer reruns since the crisis with updated reports from the gulf, will include reports from Rather on Sunday ...

ABC News anchor Peter Jennings, who has remained in New York, will also report from Helsinki this weekend ...

And Bernard Shaw will attend the summit for the Cable News Network ...

Speaking of the Anchors"ABC World News Tonight With Peter Jennings" finished first in the network news race for the 34th week in a row with a 10.0 rating and a 21 share. "CBS Evening News With Dan Rather," which had closed the gap to a mere two-tenths of a ratings point the previous week (the closest Dan had been to P.J. since the last CBS win -- in January), did a 9.3/20, while "NBC Nightly News With Tom Brokaw" remained in third at 8.7/19 ...

ABC News wants us to know that the Monday Night Football game wiped out the West Coast affiliates for the night ...

First Lady Barbara Bush yesterday revealed she keeps her eye on network news. Visiting the ABC News bureau for a radio appearance, she had some kind words for NBC News's "postcards" from the troops in Saudi Arabia (which give the troops a chance to say "Hi, Mom" on "NBC News at Sunrise," "Today" and "Nightly News"), the major push by CBS News this week for "Project Education" and the continuing "American Agenda" feature on "ABC World News Tonight" ...

It seems like only 100 years ago, but Geraldo Rivera will celebrate his 20th anniversary as a TV journalist on Monday. Tribune Entertainment, which syndicates his "Geraldo" show, is throwing him a party at the 21 Club in New York that night, right after the first show of the new season ...

Channel 26's "Pledge-Free August Campaign" wound up raising $120,160, short of the goal of $150,000 ...

The pledge-free pledge drive, which used two 900 numbers, did attract 3,279 new members ...

ABC Entertainment has renewed "Into the Night Starring Rick Dees" for another 13 weeks. The late-night show premiered July 16 ...

Channel 7 here will continue to carry the program but as of Sept. 24, WJLA introduces the syndicated "My Talk Show" half-hour at midnight, following "Nightline," which will move the renewed Dees to a 12:30 start time ...

The Second City production "My Talk Show" is described as a cross between "Saturday Night Live" and "Mary Hartman, Mary Hartman." The Dees show has not been able to hang on to the Ted Koppel audiences (which have been increasing due to the Persian Gulf crisis, of course) but WJLA isn't giving up on it yet ...

NBC, with seven shows in the top 10, won five nights and easily took the week ending Sept. 2 with a 10.6 rating and a 20 share. CBS, which is showing some late-summer life, was second at 8.8/17, just ahead of ABC, at 8.7/17. FOX averaged a 5.3/10 ...

NBC won all nights save Sunday (CBS) and Friday (ABC) ...

The best FOX could do, since "The Simpsons" moved to Thursday night against Mr. Cosby, was a 29th place finish for "Married ... With Children." "The Simpsons" finished in a four-way tie for 53rd. The "preview" of FOX's "Parker Lewis" tied for 51st while "True Colors" previewed in 58th ...

Dan Rather's primetime interview on CBS News with Iraqi President Saddam Hussein also tied for 53rd ...
