It’s hard to tell which is getting more Internet coverage this week: the earthquake in Haiti or the earthquake at NBC.

Yesterday, citing lots of "sources with firsthand knowledge of the situation who don’t want to give their names because they are terrified of Jeff Zucker, or they making it up," it was announced that Jay Leno will return to The Tonight Show after the Olympics and all that stuff that took place between June 2009 and now will be like the season of Dallas when Bobby was in the shower and Pam was having a dream.

Oh, and Conan’s last night hosting The Tonight Show will be Friday Jan. 22. Or not.

As if all that weren’t bad enough, Rosie O’Donnell sumo’d her way into the fray yesterday while she was promoting a new documentary she has on HBO.

The AP reported, "O’Donnell, talking to reporters while promoting an HBO documentary, said she was a huge fan of O’Brien.

"If you’re privileged enough to drive the bus, you should say, ‘Thank you’ and drive it to the best of your ability, and when it’s time for them to hire a new driver, you should say ‘Thank you for allowing me to drive this as long as I did’ and pass the keys to the new guy with red hair, and not try to flatten his tires before he even gets going," she said.

"O’Donnell was even more blunt on her blog, saying Leno had bullied his way back into college so he could be the quarterback again.

"She also revealed on the blog that when Leno started on the

"Tonight" show in the early 1990s, NBC executive Brandon Tartikoff offered her the chance to sub for Leno on Friday nights as Joan Rivers did for Johnny Carson. O’Donnell said Leno nixed the idea.

"The former daytime talk show host said she has no interest in late night, particularly given what’s going on now.

"That question today is like asking if I’d want to have a vacation in Haiti," she said."

Speaking of Haiti, if you want an indication of how earth-shattering NBC’s decision to air Leno five nights a week at 10 p.m., was, take at look at this, also reported by the AP yesterday:

"The research firm Harmelin Media said local NBC stations saw their late news audience drop by an average of 25 percent in November compared with the previous year among 25- to 54-year-old viewers. That’s the demographic upon which news advertising rates are based.

"The decline was particularly steep in some of the largest markets: 48 percent in New York, 43 percent in Los Angeles and 47 percent in Philadelphia.

"The report calculated that over a three-month period, the Leno experiment would cost these stations collectively $22 million. The 10 stations that NBC owns and operates would lose something like $570,000 per week, the report said."

Now, that’s not funny.

What is funny is some of the stuff that the late night hosts are lobbing, at each other and at themselves. Jimmy Kimmel on Tuesday wore an exaggerated fake chin to play Leno and joked that he was taking over all late-night shows, including Kimmel’s, and announced that ABC stands for "Always Bump Conan."
 

Last night, Kimmel appeared on Leno, appearing by satellite for Leno’s "Ten at Ten" question-and-answer segment. According to the AP, "the ABC late-night host was asked to relate his best prank ever. Kimmel replied that he told a guy five years ago that he’d give him his show, and "then I took it back."

"Kimmel also joked that Leno had "$800 million, for God’s sake," and advised him to leave other hosts’ shows alone."

I need to start watching all the shows, apparently, since the jokes are flying thick and fast. The AP says, "O’Brien did some pummeling of his own Thursday, in what is becoming a pattern for him and Leno.

"Hi, I’m Conan O’Brien, NBC’s ‘Employee of the Month,’" he said in his monologue. "There’s a rumor that NBC is so upset with me, they want to keep me off the air for 3 years. My response to that is, if NBC doesn’t want people to see me, just leave me on NBC."

"Leno delivered a punch in his monologue: "Welcome to the new show, ‘I’m a Celebrity, Get Me Off NBC!’" he said."

There was one concrete development Thursday. NBC announced what will replace Leno at 10 p.m. after the Olympics are done at the end of February.

"Law & Order" will return after the Games on Monday, March 1, with a two-hour episode airing at 9 p.m. The show, in its 20th season, will begin airing regularly at 10 p.m. the following week. (This change makes me sad, since I have come to love my Friday night L&O).

The new drama based on the Ron Howard movie, "Parenthood," with an ensemble cast including Lauren Graham and Peter Krause, will debut 10 p.m. Tuesday, March 2.

L&O: Special Victims Unit will return to 10 p.m., where it belongs, Wednesdays, starting March 3.

The other new 10 p.m. show, "The Marriage Ref" with comedian Tom Papa, will air Thursdays beginning March 4 after a Feb. 28 sneak peek following the closing ceremony of the Olympics. This is the Jerry Seinfeld produced "reality show."

"Dateline NBC" will air 9-11 p.m. Fridays starting March 5.

What’s your take on the whole mess? And are you tuning in just to see who will say what next?
