Here's something to think about as the media furor continues over the Rather-Bush shouting match on CBS Monday night:

In New York, "CBS Evening News" registered an 8.8 rating during the first 15 minutes (just as Dan and George really got going after a tedious introduction) and fell off to a 7.9 for the last 15 minutes as they continued to argue -- a loss of about 61,000 TV homes ...

Meanwhile, "NBC Nightly News," which goes head-to-head with CBS News at 7 p.m. in that market, stayed at a 10.0 rating (687,810 homes) for the full 30 minutes ...

Here in Washington, on Channel 9, "CBS Evening News" at 7 p.m. did an 18.1 over the first 15 minutes and then dropped to a 17.0 as the Bush-Rather battle continued -- a loss of 18,000 homes. Meanwhile, on Channel 4, Tom Brokaw & Co. at 7 p.m. climbed from a 9.6 to a 10.5 for the last 15 minutes -- picking up 15,000 homes ...

Fred DeMarco, a former vice president and general manager of Channel 4 here, has been named vice president and treasurer of the Corporation for Public Broadcasting ...

DeMarco was elected by the CPB board during its current meeting in Corpus Christi, Tex. For the past year, he has been a CPB consultant ...

A 20-year veteran of NBC, DeMarco was station manager at NBC-owned WMAQ in Chicago when he was moved to WRC as the top executive in 1984. In October 1986, he was replaced by Jerry Nachman and left the network shortly thereafter ...

Earlier in his career at NBC in New York, DeMarco worked in budgeting and financial analysis and at one time was chief financial member of the network's satellite interconnection committee, which developed the initial studies to distribute NBC programs by satellite ...

This was probably a key element in DeMarco's selection, since public broadcasting needs a satellite replacement by 1991 and has so far not had much success with a budget-cutting Congress in obtaining funds for the project ...

DeMarco succeeds Donald E. Ledwig, who retained the treasurer's post after being named acting president and then president of CPB, starting in November 1986 ...

Meanwhile, the 50-member WETA board of trustees yesterday named Sharon Percy Rockefeller chairman ...

A key figure in public broadcasting since the mid-1970s, Rockefeller served as CPB chairman from 1981 through most of 1984. Currently a member of the PBS board, she served on the WETA board from 1974 until 1977 and was reelected in 1985. She has been vice chairman of the board and vice chairman of the development committee since then ...

On the WETA board, she replaces E. William Henry as chairman ...

In one last tad of public broadcasting news, Herbert Schmertz, vice president public affairs of the Mobil Corp. and a member of the corporation's board of directors, announced yesterday he is leaving Mobil on May 1 to form his own company, which will represent corporations and foreign governments and produce TV programs and theatrical movies ...

Schmertz "plans to devote a substantial amount of his time acting in an advisory capacity on behalf of Sen. Robert Dole's presidential candidacy," according to an announcement ...

And what has this to do with public broadcasting, you may well ask? During Schmertz's 22 years with Mobil he is credited with creating "Masterpiece Theatre" (in 1971) and "Mystery!" (1980), two of the grace notes on the PBS schedule every season ...

WGBH in Boston, which distributes the two programs, was quick to assure grace note fans yesterday that much as WGBH will miss Schmertz, the station has a funding commitment from Mobil for the two series through calendar year 1990 and is "currently negotiating an extension of that commitment through 1993" ...

Also in the News

NBC News announced yesterday that Garrick Utley will replace Boyd Matson as coanchor of "Sunday Today" beginning Feb. 7 ...

Matson will become senior correspondent for the "Today" show. NBC News said Matson "will be developing special reports on the mood of the country and the issues that face us in this important political year." He will also substitute for "Today" anchor Bryant Gumbel while Gumbel prepares for his Summer Olympics assignment, starting the week of Feb. 29 ...

In a statement yesterday, NBC News president Larry Grossman said that "as important as 'Sunday Today' is, we need to see more of Matson six days a week ... Boyd is a terrific and versatile asset for us and we look forward to his continued and expanded contributions to 'Today,' 'Sunday Today' and 'NBC Nightly News' ...

(Translation: too many NBC affiliates thought Matson and coanchor Maria Shriver together seemed a little too youthful to compete with CBS' "Sunday Morning," so the network went for NBC veteran Utley, who should alter the tone and add weight to the anchor team) ...

Utley is currently principal correspondent on "Sunday Today" and also anchors the Sunday edition of "NBC Nightly News" and is the regular substitute for Tom Brokaw on "NBC Nightly News With Tom Brokaw" ...

Grossman also announced yesterday that Sid Feders has been named executive producer of "Sunday Today," replacing Mary Ryan, executive producer of "Today," who has been acting executive producer of the Sunday program since it debuted last September ...

Feders has recently served as senior producer for NBC documentaries, including the highly rated Connie Chung special "Scared Sexless" ...

Incidentally, since "Sunday Today" moved to a 9 a.m. start on four NBC-owned stations in major markets, the series has met the 2.0 national rating average it had promised advertisers ...

As thousands slumbering in their breakfast nooks attest, we're rather Personnel Oriented this morning, TV Column fans ...

Nevertheless, find it in your slow-beating hearts to also welcome Carin Dessauer, who has joined the ABC News bureau here as a reporter/researcher for political coverage. Carin has been a reporter for the Washington-based "The Political Report" ...

"CBS Evening News With Dan Rather (and Without George Bush)" won again in the network news race last week with a 12.5 Nielsen rating and a 22 percent audience share. It was the 18th straight week at the top for CBS. In its first peek out of the cellar in a month, "NBC Nightly News With Tom Brokaw" was second at 11.4/20, just ahead of "ABC World News Tonight With Peter Jennings" at 11.3/19 ...

CBS had its best week since Oct. 5 but it was still NBC on top for the week ending Jan. 24 with a 16.3 rating and a 26 percent audience share ...

CBS was second at 15.0/24, while ABC trailed at 12.3/20 ... even though a fresh episode of "Moonlighting" vaulted that peculiar series to 11th from a 32nd-place finish the previous week ...

NBC, which can't lose for winning, saw "L.A. Law" score its highest rating ever ...

In other highlights and lowlights for the week, NBC's "The Child Saver" tied for 28th, the 30th anniversary of the Country Music Association on CBS tied for 39th and the premiere of CBS News' "48 Hours" was 53rd (with a 12.1/18) last Tuesday night ...

ABC's football saga "What Price Victory" was 59th and ABC's "A Father's Revenge" was 62nd ...

The Final And At This Stage In The Game Probably Fatal Five included the NBC News special on America's homeless, "Home Street Home," 67th, followed, in order, by CBS' "The Law & Harry McGraw," NBC's "The Storyteller" and ABC's "Sledge Hammer!," tied for 69th; and ABC's "The Charmings," who were anything but, and who finished in 71st and last place for the week ...
