The very rich are quite different from the rest of us in many ways, and one of them is what they watch on television. They like shows that most others don’t.

Programs enjoyed by the very rich include ABC’s “Saturday Night Football” and “What About Brian” as well as NBC’s “Friday Night” and “30 Rock.”

All four rank in the top 15 among affluent viewers measured on median income, but none ranks higher than 80th among the general household population.

That’s according to a report from Magna Global, using analysis of Nielsen Media Research ratings to rank programs according to their median household income among adults 25-54.

While a couple of the shows matched with the general viewing public’s favorites, like No. 1 “Desperate Housewives,” most were quite different.

That skew in preferences is also seen in the networks favored by rich viewers. Though NBC has slid from first to fourth place in 18-49s over the past few years, it ranks No. 2 in median household income behind only ABC, and it has seven of the top 20 shows in median income.

“Affluent programs are important to advertisers because [their viewers] have more money to spend,” says Steve Sternberg, executive vice president of audience analysis at Magna. “But obviously, they are more important to some advertisers than others.”

ABC’s audience has a median income of $64,000, based on adults 25-54 in fourth quarter, compared to NBC’s $60,000, CBS’s $59,000, Fox’s $53,000 and the CW’s $45,000.

Among middling performers with affluent viewers propping up NBC is “The Office,” a comedy that so far this season ranks only No. 28 among all shows in the 18-49 demographic. But it is tied with ABC’s “Housewives” at No. 1 in affluence, with its viewers having a median income of $70,000.

More telling, “Scrubs” ranks only No. 51 among 18-49s but No. 6 in affluence with a median of $68,000, tied with ABC’s “Grey’s Anatomy” and “Lost” and NBC’s “Studio 60 on the Sunset Strip,” which is partly why it is remarkably in its sixth season despite never having been more than a modest performer for NBC.

It has consistently had a high median income in the regular reports issued by Magna over the years.

Shows like “Scrubs” probably give the creators of a few first-season shows on NBC and other networks some hope of survival.

NBC Thursday sitcom “Rock,” for instance, is far from a sure bet for renewal. For the season it’s tied at No. 85 in the 18-49 demographic, but its viewers have a median income of $65,000, enough to be tied at No. 11 in affluence with several other shows.

Also doing well in affluence but not necessarily overall ratings is ABC’s “Brian,” a weak drama stuck at No. 82 in the ratings so far this season but, like “30 Rock,” tied at No. 11 in affluence.

Of course, many factors go into whether or not a show makes it another season, notably its overall rating and its ability to retain viewers from lead-in programs. Recent shows with affluent viewers like Fox’s “The O.C.,” ABC’s “Six Degrees” and CBS’s “The Class” are either already gone or in their final throes.

Sternberg says programs like “Studio 60” aren’t likely to see a second season despite their viewers’ affluence.

“If [‘Studio 60’] had held onto its initial audience, I would say yes,” he says. “But since it has been declining I have to say it’s borderline at best.”
