Number one NBC announced yesterday it will begin premiering its fall schedule on Sunday, Sept. 13, with episodes of "Our House," a one-hour "Family Ties" and the two-hour pilot for the new "Private Eye" ...

The primetime season gets under way "officially" Monday, Sept. 21, this year ...

Wednesday, Sept. 16, "Highway to Heaven" returns, along with "A Year in the Life," adapted as a series from last year's critically acclaimed miniseries, and "St. Elsewhere" ...

"Night Court" debuts on Thursday, Sept. 17; "Rags to Riches" returns on Friday, Sept. 18, along with the debut of "Private Eye" in its regular 10 p.m. time slot ...

On Saturday, Sept. 19, "The Golden Girls" returns along with a glimpse of "Mama's Boy" ...

The latter is one of at least three "designated hitter" series chosen earlier this year that will air once a month through the fall before probably joining the regular NBC schedule as replacement series in January. The others are "Bronx Zoo," which gets a look on Sept. 24, and "Beverly Hills Buntz," which shows up Oct. 29 ...

The new "My Two Dads" will debut Sunday, Sept. 20, while "ALF" and "Valerie" return the next evening. "Matlock" and "Crime Story" show up Tuesday, Sept. 22; while on Thursday, Sept. 24, much of NBC's dynamite Thursday schedule, including "The Cosby Show," the new "A Different World" and "Cheers," shows up along with designated hitter "Bronx Zoo" ...

"Miami Vice" debuts on Friday, Sept. 25; while "Facts of Life," "227" and the new "J.J. Starbuck" debut Saturday, Sept. 26 ("Starbuck" moves to its regular 9 p.m. time slot on Tuesday, Sept. 29) ...

"Amen" and "Hunter" premiere Saturday, Oct. 3, but "L.A. Law" won't debut until Thursday, Oct. 15 ...

NBC will also launch 27 specials and movies as well as three miniseries starting Sept. 17 and running through Dec. 28 ...

These include the Miss America Pageant on Saturday, Sept. 19 ...

The schedule was released as NBC Entertainment president Brandon Tartikoff met with TV writers out in Beverly Hills for the annual press tour ...

He also announced that "The Days and Nights of Molly Dodd" (that's the good one, without the laugh track, which makes it even better) has been picked up for a second season ...

Tartikoff said "Molly Dodd" reflected a "mini-trend" of half-hour drama series with comedy overtones that will be noticeable this fall. He also included NBC's "Beverly Hills Buntz," CBS' "Frank's Place" and ABC's "Hooperman" in the new, if limited, genre ...

Tartikoff said he and Bill Cosby are both quite aware that the upcoming fourth season of "The Cosby Show," the number one program on network television, will be its most critical and important ever ...

He said Cosby signaled his concern by summoning his writers to San Francisco six weeks earlier this year to get to work on the scripts for the fall ...

Tartikoff also said he has complained about misleading network promotions -- seen in the Washington market -- claiming that "primetime begins at 7:30 on NBC" this fall ...

The promos refer to the fact that on the five NBC-owned stations, including WRC, the network has put together a "checkerboard" of five different programs for the 7:30 weeknight time slot, and in no way is extending the 8-to-11 primetime period on the more than 200 affiliated NBC stations (all 200 of which would yell bloody murder if the network tried to take that lucrative half hour starting at 7:30, when game shows and other local programming choices are aired for very big local ad bucks) ...

Also in the News NBC News president Larry Grossman has dropped the idea of talking ABC and CBS into joining in a pool for exit polling in the national elections next year as a cost-cutting measure ...

Grossman had taken the lead earlier in successfully persuading the other two networks to rotate coverage of the Iran-contra hearings ...

ABC News had quickly rejected the exit polling pool idea, saying the polling was a journalistic function for each network news division. CBS News, which still wasn't commenting publicly on the matter Friday, reportedly had its own idea for some kind of an exit poll pool that didn't conform to the Grossman proposal ...

The scuttlebutt on Friday was that NBC president Bob Wright had personally called CBS Inc. president Laurence Tisch and Capital Cities/ABC Inc. chairman Tom Murphy, asking consideration of Grossman's proposal. Tisch reportedly was initially receptive to the idea, while Murphy said he was deferring to his news executives for a decision in the matter ...

PBS, with 35, led nominations announced yesterday for the News and Documentary Emmy Awards, which will be awarded early in September in New York under the auspices of the National Academy of Television Arts & Sciences ...

CBS received 32, ABC 24, NBC 18 and syndicated programs two ...

Programs with the most nominations included "CBS Evening News With Dan Rather," with eight; and ABC News' "Nightline," ABC's "20/20" and the National Geographic specials on PBS, each with six ...

In recent weeks, Captain Airwaves has published items about two prospective projects of interest to Washington viewers. Both, to C. Airwaves' surprise, prompted a lot of inquiries but only this morning are we able to supply the information sought ...

Regarding the idea from David Milch, coproducer of "Hill Street Blues," for a drama series focusing on a top Washington public relations firm, those interested in contacting Milch can write to him at:

CBS MTM Studios, 4024 Radford Ave., Studio City, Calif. 91604 ...

The other project involves Steve Friedman, former executive producer of NBC's "Today" show, who is joining Grant Tinker and Gannett to put together a weeknight magazine show for September 1988, probably using the format of Gannett's successful USA Today paper. To contact Friedman write:

The Culver Studios, 9336 W. Washington Blvd., Culver City, Calif. 90230 ...

Bill Redeker, one of 14 CBS correspondents dismissed in the March massacre at CBS News, has signed as co-anchor for a new 10 p.m. newscast at the Fox-owned KTTV in Los Angeles. He'll team with Andrea Maverson, who, like Bill, has previously worked for both ABC and CBS ...

Mayor Marion Barry's appearance on "Donahue" Thursday in a discussion of welfare apparently helped boost the show's ratings on Channel 9. The appearance from 1 to 2 p.m. (CBS was carrying the Iran hearings that day) scored a 9.4 Nielsen rating and a 27 percent audience share, about double the usual "Donahue" count in this market ...

The actors who do the voices for more than two dozen animated series like "The Smurfs" and "The Cabbage Patch Kids" have settled their five-week strike against four producers ...

The Screen Actors Guild said the actors got a new three-year contract, a 10 percent pay raise, generally shorter recording sessions and a 10 percent bonus when they're required to do three main characters in one session ...

In addition, most recording sessions will be shortened from eight hours to four ...

Exceptions: Calls for the first show of any new series, song-and-dialogue sessions and specials. Actors will also be required to perform "pickups" of muffed or flawed lines on an unlimited basis without additional compensation ...

About one third of the 300 actors who originally walked out June 15 went back to work earlier this month when Hanna-Barbera, the largest animation studio in Hollywood, settled for what SAG said were about the same terms ...

Last week's settlement was with Disney, Marvel Productions, DIC Enterprises and Filmation. The actors are expected to return to work today and ratify the contract later, if the producers signed the contract on Friday as expected ...

Although the strike hit just when studios were in their prime production period for the fall season, an SAG spokesman said, "I think with some hard work, we're going to catch up" ...
