CBS Entertainment yesterday announced "The Oldest Rookie" is headed for the Old Series Home and a well-deserved rest following its Wednesday, Jan. 6, broadcast ...

And "The Law and Harry McGraw," which was headed for the Home permanently as of Nov. 19, will now return in "The Oldest's" old time slot on Wednesday, Jan. 13, at 8 p.m. "McGraw's" last outing in its current 10 p.m. Tuesday slot will be Dec. 29 ...

CBS recently ordered four additional "McGraws" but there could be a couple more so the exact length of "McGraw's" reprieve from the Home could not be determined yesterday. CBS yesterday promised that "The Oldest Rookie" will return. Somewhere. Sometime ...

Through last week, "McGraw" was ranked 56th among 80 series offered so far this season on the three networks. "Oldest" was tied for 61st ...

Speaking of the Old Series Home, there was quite a fracas out there yesterday in the West Wing ...

That's where the crew from CBS' "The Morning Program" has settled in after going off the air two weeks ago. Yesterday, right after lunch, they were told that the very first national Nielsen ratings for their successor, "CBS This Morning," showed the new program with a 2.2 Nielsen rating and an 11 share for the week ending Dec. 4 (each rating point represents 886,000 TV homes) ...

That's barely a tad up from the 2.1/10 "Morning Program" averaged over the last three months of its existence ...

It took an impassioned plea from the Home supervisor to "give the new bunch a couple of weeks, at least, for heaven's sake" and a round of hot cocoa to finally quiet the "Morning Program" crowd down ...

Meanwhile, NBC's "Today" show won the morning network race for the third week in a row with a 4.6/22, followed by ABC's "Good Morning America" at 4.4/21 ...

In other news from the Home, where they have the new quarters all ready for occupation (with plenty of extra blankets), it was learned NBC Entertainment has postponed its announcement on series replacements, originally due out yesterday, until probably Monday ...

Tomorrow at 11 a.m., C-SPAN will air an hour of Wednesday night's black-tie dinner at the National Press Club, where David Brinkley received the 15th annual Fourth Estate Award from the club's board of governors honoring him as "the person who has achieved distinction for a lifetime of contributions to American journalism" ...

Brinkley was "roasted" by former Democratic Party head Robert Strauss, columnist George Will and Lane Kirkland, president of the AFL-CIO ...

If the segment, which will run about 10 minutes, catches on, Five is thinking of turning it into a weekly half-hour program that could be syndicated ...
