ABC Entertainment has rescued "Lady Blue" from the clutches of NBC's Thursday night schedule and dispatched her to Saturdays at 9 p.m., starting Nov. 16 . . .

"Lady Blue" will occupy the spot vacated by "Lime Street," which has gone on a much-needed vacation until after the first of the year . . .

"Lady Blue" had its final outing against "Cheers" and "Night Court" last night . . .

The World Series, a repeat of "Goldfinger" and an episode of the "North and South" mini-series will fill Thursdays until "Dynasty II: The Colbys" moves in on Nov. 21 . . .

"Lady Blue" has finished 53rd, in a tie for 60th and tied for 53rd in the first three weeks of the new season against the NBC juggernaut . . .

In another move to blunt, ever so slightly, the NBC Thursday impact, ABC's "20/20" will put a British-filmed interview of Prince Charles and Princess Diana at 8 p.m., up against "The Cosby Show" the night of Nov. 7 as a prelude to another episode of "North and South" . . .

The finale of the Kansas City-Toronto playoff series Wednesday night -- wrapping up NBC's share of the baseball postseason -- averaged a 19.9 rating and a 31 percent audience share in Nielsen's top 10 markets . . .

ABC, with "Dynasty" averaging a 24.6/36, won the night in the big cities with a 20.7/31 average. NBC, pregame show and all, averaged a 17.7/27, while CBS took another Wednesday night bath, averaging only a 10.2/15 . . .

Earlier Wednesday, the St. Louis-L.A. National League playoffs ended after only six games . . .

As a result, NBC had to go with its regular prime-time schedule last night, which foreshadows a previously unplanned Thursday night of series reruns, come December . . .

According to the national Nielsen ratings for Tuesday, the Kansas City-Toronto game averaged a 20.9/32 as NBC won the evening . . .

NBC averaged a 20.3/31 from 8 to 11 on Tuesday, compared to ABC's 17.1/26 and CBS' 15.3/23 . . .

Five of the nation's biggest corporations will pool up to $20 million to produce five "quality" commercial TV specials next year . . .

The consortium includes American Telephone & Telegraph, Armstrong World Industries Inc., Ford Motor Co., The Gillette Co. and Xerox Corp. . . .

The rising cost of TV productions has made sponsorship of several shows a year "too big a commitment for a single company," according to Tom Ryan, who organized the group and whose Red Oak Productions in Boston will hire writers, producers and directors for the programs . . .

The programs, to be produced by the companies, should be ready for the 1986-87 season . . .

The networks are waiting to see the finished product before committing to airing the shows, but have expressed interest, according to Ryan. . .

In the 1950s, major corporations routinely pooled funds for shows like "Philco Television Playhouse" and "Texaco Star Theater". . .

The five companies together spend some $1.4 billion for advertising annually, much of which goes to TV . . .

In his opening remarks, Tinker told the employes they "had saved the company. Just a couple of years ago we were in dire straits but now we're on a roll" . . .

WRC vice president and general manager Fred DeMarco used the occasion to introduce Manny Sternfeld, an NBC employe for 28 years and for more than a decade WRC's director of finance . . .

Sternfeld will retire at the end of the month. He received a standing ovation via two-way TV from employes at the seven stations . . .

Speaking of WRC, the Channel 4 volleyball team, which includes DeMarco, Bob McBride, Jim Upshaw and other on-air talents, will open tonight's program at George Washington University featuring the U.S. women's Olympic volleyball team and a team from Japan . . .

WRC will play a team from radio station DC 101 at 8 p.m. at the Smith Center . . .
