Conan O’Brien made a triumphant exit from NBC Friday night, accompanied by one of the most impressive outpourings of support by younger viewers that any late-night host had ever seen  and Mr. O’Brien was effusive in his thanks for their backing. 
 
 But he might have said: Where were you when I needed you? 
 
 In the tumult that surrounded NBC’s late-night shake-up last week, one thing was certain: If even a small fraction of the additional younger viewers who flocked to Mr. O’Brien’s show last week had turned up regularly in his earlier ratings results, he would almost surely still be hosting “The Tonight Show.” 
 
 Instead, for most of this past fall, Mr. O’Brien struggled to command the young viewers he needed to counter a falloff in overall audience numbers. 
 
 While he began to drop behind his chief late-night competitor, David Letterman on CBS, among total viewers, it was more alarming to NBC that Mr. O’Brien was not consistently beating Mr. Letterman in several important advertising-sales demographic groups  viewers 18 to 49 and 25 to 54. (He did beat Mr. Letterman virtually all the time in the 18-to-34 group.) 
 
 But to NBC’s surprise and disappointment, Mr. O’Brien fell behind his predecessor, Jay Leno, even among those 18-to-34 viewers, the group expected to be his core constituency. (From his start in June through the end of 2009, Mr. O’Brien averaged 716,000 viewers in that age group, down from the 759,000 Mr. Leno averaged the previous six months.) 
 
 Several television researchers said in interviews that this outcome might have been easily predicted, not because Mr. O’Brien does not appeal to younger viewers  he clearly does, as evidenced by the large numbers he attracted for his closing shows  but because regularly assembling those young adult viewers in significant numbers in the late-night hours has become a daunting, if not impossible, task. 
 
 “The 18-to-34 group is so difficult to attract and the lower half, 18 to 25, is the hardest of all,” said Jack MacKenzie, the president of the millennial strategy program for the research firm Frank N. Magid Associates. 
 
 Compounding the problem, said a senior research executive for another company, was the fact that Mr. O’Brien was especially appealing to young men. “And that group doesn’t watch television very regularly,” said the executive, who asked not to be named because his business competes with NBC. 
 
 Instead of watching Mr. O’Brien most nights, Mr. MacKenzie said, those young viewers have been watching everything from similar shows like “The Colbert Report” on Comedy Central, to cartoons on the “Adult Swim” franchise on the Cartoon Network, and the ever-present array of sports and sports news on ESPN and its sister channels. 
 
 In comparison with the 719,000 viewers in the 18-to-34 group that Mr. O’Brien had been averaging, Stephen Colbert on his “Colbert Report,” in the same six- month period in 2009, averaged 746,000 viewers ages 18 to 34. The cartoons on “Adult Swim”  mostly “Family Guy” and “Robot Chicken”  averaged 619,000 of those viewers. ESPN from 11 p.m. to 1 a.m., with varied programs that included both live sports events and editions of the highlights show “Sports Center,” averaged 614,000 viewers in that group. 
 
 And dozens of other cable channels took other slices of the under 35 viewers. 
 
 “What you’ve seen in recent years is increased spending by all these cable channels for original programming,” Mr. MacKenzie said. “And besides having a double revenue stream of subscription fees and advertising, the cable channels have the luxury of targeting specific audiences. Broadcasters don’t.” 
 
 Fans of sports, for example, were watching ESPN many nights instead of Mr. O’Brien; and cartoon lovers were hooked on “Adult Swim.” 
 
 But even all the competition on cable did not represent the total distraction for young viewers that Mr. O’Brien had to contend with. The senior research executive pointed to outside attractions like video games that vie for the attention of young, especially male, viewers. And CBS executives have in the past identified the growing tendency of owners of digital video recorders to use the time after late local newscasts to play back programs recorded earlier that night or on previous nights. 
 
 A spokeswoman for Nielsen Media Research pointed to a study the company released last year that cited the peak hours for DVR playback. The late-night hours showed the highest percentage of playback outside the prime-time hours, with about 7.6 percent of playback taking place from 11 p.m. to 12 a.m. 
 
 As an executive from one of NBC’s rival networks put it: “Conan didn’t just have to worry about Letterman; he had to worry about ‘House.’ People are playing back episodes of shows like ‘House’ in late night.” 
 
 Add to all the other issues the fact that Mr. O’Brien’s young fans did not really have to watch television to see him. His shows were made available later on Web sites like Hulu. And his best comedy bits would frequently be posted on other sites  and passed around by fans  shortly after they appeared. 
 
 Mr. MacKenzie added that NBC did Mr. O’Brien no favor by moving Mr. Leno to the 10 p.m. hour this fall. “That meant there was a show very similar in style to his on the air before him,” he said. 
 
 In his run on “The Tonight Show,” Mr. Leno managed to attract the largest audiences in virtually every age group, though his ratings too showed signs of falling off in his later years on the show. But his was always the first show of the late-night talk variety on NBC each night, Mr. MacKenzie. 
 
 That will happen again when Mr. Leno returns to “The Tonight Show” on March 1. But Mr. MacKenzie had some words of caution for NBC. 
 
 “A generational switch is coming,” he said. “The baby boomer audience that has mostly been the Leno audience is going out. The Conan audience is becoming more influential  even if they aren’t watching television the same way the previous generation did.” ||||| stars Sally Field as a beleaguered factory worker who risks her job and everything she’s worked for in order to correct injustices in the workplace. She is everywoman, standing up to The Man to do what’s right. Not just for her, but for the millions just like her all over the country. Those oppressed masses just trying to put food on the table, the ones without health care, the ones struggling to make ends meet. The ones who just want a fair shake. Somebody had to have the courage to take on the Big Baddies running the show. In 1978, that somebody was Norma Rae. In 2010, it’s Conan O’Brien? 
 
 When did Conan O’Brien become Norma Rae? For those of you who don’t remember this 1978 film, Norma Rae 
 
 How did a Harvard-educated, multi-millionaire late night talk show host magically transmogrify into a guy who got laid off at the local car plant? The overreaction to Conan’s departure has been kind of astounding; as a nation, are we really that concerned about who hosts “The Tonight Show,” a television program that stopped being culturally relevant around 1986? 
 
 And let’s not forget, it’s not as if Conan was cancelled. He quit. He walked away from “The Tonight Show” because he rightly or wrongly felt that moving the show half an hour later would destroy the show’s integrity. Okay, fine. But let’s not act as if he’s leading a sit-in at a segregated lunch counter. It’s not that big a deal. 
 
 Yes Americans believe in fair play. Fair play means making a deal and sticking to it. Conan got “The Tonight Show,” and therefore he should keep it. I agree with that. But Americans also believe in capitalism, and when fair play bumps up against capitalism, capitalism usually wins. It did this time. 
 
 To my mind, there are two reasons why Leno has come across looking as bad as he has throughout the last few weeks. The first is that he seems like an opportunistic pig for agreeing to move back to 11:30. He should have packed up his funny headlines and gone home. The other reason is that Conan has been much funnier about the whole thing. His letter to the Times was funny, his monologue jokes have been funnier, and whereas Leno has come across as needy and desperate, O’Brien’s departure seems, if not exactly classy, then at least in classy’s neighborhood. Of course it’s easy to be classy-ish when you and your staff are walking away with forty million dollars. 
 
 I think the deeper reason people are so inflamed by this petty war is that Conan in his own way has come to represent the aggrieved, the injured, the wrongly terminated. I think there is a sense in this country that giant corporations are ruining everything, even late night talk shows. Something so insignificant takes on greater importance because I think on some level, “The Tonight Show” actually has become a very flawed stand-in for all the jobs lost to corporate greed, arrogance, and stupidity. We see Conan as a victim because we feel as though, like us, he wasn’t given a fair shot. If a guy like that, a guy who has everything, can be downsized and demoted, what hope do the rest of us have? 
 
 Moreover Leno is installed back in his abdicated throne. It feels like a coup, a particularly unfunny coup. And above him, all the top brass still have their jobs. Just like all the top brass in every other failed or bailed-out corporation. It feels unfair. And it makes people mad. 
 
 Sure it’s a shame it didn’t work out for Conan, the most creative talk show host since David Letterman, and I think it’s great he took a principled stand against NBC, but is this really the stuff of rallies? Is this really where we want to spend our political capital? If you have the energy to protest Conan O’Brien’s departure in Burbank, shouldn’t you maybe think about spending some time chanting outside General Motors or Goldman Sachs? Or Congress? This is the cause you want to get involved with? Instead of holding up placards with the Masturbating Bear on them, maybe donate a pint of blood. It’ll be a lot more helpful to somebody. 
 
 Conan is an unlikely hero of the working man but at this point, when heroes are far more likely to be squashed than celebrated like Norma Rae, as sad as it sounds, he might actually be the closest thing we’ve got.
– Conan O’Brien joins the ranks of the unemployed today, so the ousted Tonight Show host now has plenty of time to track the backlash and second-guessing about the TV shell game. Jay Leno remains the villain of the piece, but the hard truth is that O’Brien never drew the numbers of young viewers to his time slot that NBC had hoped for. “The 18-to-34 group is so difficult to attract and the lower half, 18 to 25, is the hardest of all,” a strategist told the New York Times. The increasingly fractured TV landscape didn’t help. Competition is now fierce for the audience Tonight Show producers once took for granted. O'Brien has been buffetted by the same economic realities most American are grappling with, making him a "Harvard-educated, multi-millionaire late night talk show host" who was "magically transmogrified into a guy who got laid off at the local car plant," blogs Michael Ian Black.
