Pirates of The Caribbean - On Stranger Tides - Soundtrack by Rodrigo y Gabriela

The much anticipated collaboration between Rodrigo y Gabriela and Hans Zimmer on the soundtrack to one of the biggest movies of the summer Pirates of The Caribbean On Stranger Tides is out now. The soundtrack combines several brand new Rodrigo y Gabriela compositions and many of the original Pirates themes from the previous movies with the added unmistakable guitar wizardry of Rod and Gab.



The movie sailed into the Cannes film festival last week and is out now in the US.


Rod and Gab gave 'The Pirate That Should Not Be' a live outing with an orchestra on last week's Tonight Show with Jay Leno.

Taylor Swift's Sexy Shirtless Tattooed Serenade by Baby Oiled Dane Cook! (VIDEO)

Taylor Swift got quite a surprise last night on 'the Tonight Show with Jay Leno'. Comedian Dane Cook threw off his shirt, strapped on his guitar and serenaded her with the 'We Love You Taylor' song, which is sure to be a #1 download on iTunes this holiday season...or not, but it was kinda funny and cute. And Dane appears to have (temp) tattooed Taylor's pretty face on his chest, which is awesome.

Schwarzenegger: 'No One Cares If You Smoke A Joint'

Arnie burns one down in the documentary "Pumping Iron"

​
In California, "No one cares if you smoke a joint or not," Governor Arnold Schwarzenegger said Monday night on The Tonight Show with Jay Leno.

The Governator made the remark while discussing Prop 19, which would have legalized adult recreational pot use in the state, reports Mary Dooe at CBS News.

"Proposition 19 went a little bit too far, I think," Schwarzenegger said of the failed measure. But he added a note of hope for the future.

"Propositions don't die because the idea is bad, it just dies because it is written wrong," the Governor added.

Arnie said his decision to sign a bill last month that reduces marijuana possession charges for up to an ounce from a misdemeanor to a civil fine hurt Prop 19's chances of passing.

"It makes [possession] from a misdemeanor to an infraction, which is like a speeding ticket," Schwarzenegger said. "And no one cares if you smoke a joint or not."

Schwarzenegger famously appears in the body building documentary, Pumping Iron, including one memorable scene in which he is seen puffing on a joint.

California voters turned down Prop 19, 54 percent to 46 percent.

The first guest on NBC's "The Jay Leno Show" will be ... Jerry Seinfeld.

Comedian booked for Sept. 14 premiere

An NBC spokesman confirmed that Seinfeld will appear on the premiere of "Jay Leno" on Sept. 14. He is expected to sit down for a chat with Leno as well as do stand-up.

Seinfeld, who appeared on "The Tonight Show With Jay Leno" six times, has always been a marquee draw for late-night talk shows.

"The Tonight Show" featuring the cast of "Seinfeld" the night of the series' finale in 1998 drew 15 million viewers, the show's third-largest audience ever.

This time, Seinfeld is expected to promote his stand-up act at Caesars Palace on Dec. 26 and 27 as well as a "Seinfeld"-themed story arc on the next season of Larry David's HBO comedy "Curb Your Enthusiasm," which premieres Sept. 20.

Additionally, Seinfeld has a reality series for NBC, "The Marriage Ref," slated for midseason.

It is not clear yet if Seinfeld would participate in any of the new segments on the show. With his background as an avid car collector, Seinfeld might be tempted to take a spin on the show's track for "Green Car Challenge," where celebrities will race alternative-fuel vehicles.

On the first "Leno," Seinfeld will be joined by previously announced musical guests Jay-Z, Rihanna and Kanye West.

'Jay Leno Show' format revealed

Jay Leno's new comedy show will be a fast-paced hour featuring celebrity car races and comedian correspondents, among other format twists.

An energized Leno took the stage at the critics press tour in Pasadena along with network late-night head Rick Ludwin and dropped several revelations about the new program.

"The Jay Leno Show" will have a fast opening sequence, about 10 seconds, before launching into the host's monologue. There will be one celebrity guest, perhaps two at most. Musical segments will sometimes feature multiple acts performing together -- like on the Grammys when famous artists are teamed together. Leno's signature comedy bits like Jay Walking and newspaper headlines will be saved for the end of the show, where Leno will tell viewers to stay tuned for the local news (this is the only part of the show where Leno might have a desk). NBC will not air any commercials between after Leno's show and is urging local affiliates to do the same.

"When the comedy segment is over, it will literally end the show," Ludwin said. "We're giving [affiliates] the hottest hot hand off you can have."

Leno also previewed some segments, such as the advertiser-friendly "Green Car Challenge," where celebrities race against each other in alternative fuel vehicles. NBC has built a race track next to the studio where guests can compete against each other.

"You can see who is faster, Shaquille O'Neal or Cameron Diaz," Leno said.

Other segments will feature comedian correspondents doing taped segments, a bit like on Comedy Central's "The Daily Show" (though Leno rejected that comparison). D.L Hughley will report on politics from Washington, for instance, and "Hangover" actress Rachel Harris has been tapped as well.

NBC Nightly News anchor Brian Williams will also have a regular bit on the show -- "Stories Not Good Enough For Nightly News."

Leno says he's lost about 10-12 pounds running four miles every morning in training for his new show and says he had grown "complacent" while hosting "Tonight Show."

He said that contrary to some media reports, he wasn't tempted to go to ABC when his contract was up, though acknowledged having mixed feeling about NBC.

"When you change networks, [people think] you're greedy, that you wanted more money," he said. "There are things I like about the network and there are things I don't. But much like a marriage you work it out ... there's only so much pie you can eat. There was no desire to go to ABC and go against Conan [O'Brien]... because that's bitterness ... bitterness kills creativity, it kills everything. You put your head down and move forward."

Asked about the pressure of having to "save NBC" with his new program, Leno shrugged.

"Screw the network," he said.

Regarding O'Brien, however, Leno said the two have firmly remained friends, though he expects they will have a healthy rivalry this fall.

"There was never any tension between Conan and I," he said. "Will we fight like cats and dogs to get the guest? Yes ... but that doesn't mean you don't like each other. It's a game. You tease and trash talk, that's the fun part."

Ludwin also admitted that it was "premature" to declare O'Brien "The New King of Late Night" after his first week on the air.

"I think it was premature," Ludwin said. "We were very proud of the show...there were those who thought that Conan would not be broad-based enough ... he far exceeded our expectations."

Though NBC executives otherwise ducked questions about ratings expectations for the fall, Leno was pretty specific. He said he expects to beat scripted programs when they're in repeats -- if not in originals.

"Do I expect to beat 'CSI: Miami'?" he asked. "No. Do I expect to beat them in repeats? Yeah. I don't expect to get them on the straights but catch them in the corners."

Leno passionately protested the idea that his new 10 p.m. show is taking opportunities away from scripted programming talents.

"I think you have more [dramas] than ever now -- USA Network, cable, all these shows," he said "There are places to go now to get that. So I don't see that as the problem. NBC tried scripted programming at 10 p.m. The other thing that annoys me -- we use writers. Our writers are in the top 5% of the highest-paid writers in the Guild."

Leno disagreed with an idea George Lopez presented earlier at press tour while promoting his upcoming TBS late-night talk show, that a show's format should be flexible enough to open with a musical guest, such as U2.

"What a big musical guest gets you is a great studio audience, you wouldn't necessarily have a great television audience." Leno said. "If I want to see U2, I can go to VH1, or go to YouTube."

A critic, impressed by Leno's fielding of the questions, noted he seems much more confident now than his previous TCA appearances.

What's changed?

"I'm rich now," Leno said.

Jay Leno’s 3D Printer Replaces Rusty Old Parts

Jay Leno has a lot of old cars with a lot of obsolete parts. When he needs to replace these parts, he skips the error-prone machinist and goes to his rapid prototyping 3D printer. Simply scan, print and repeat.

By Jay Leno

It’s an amazing way to fabricate parts. The 3D scanner next to Jay creates a digital model of this flanged nut from Jay’s EcoJet supercar. The nut takes 20 minutes to scan and reverse model and 3 hours to print in plastic.

One of the hardships of owning an old car is rebuilding rare parts when there are simply no replacements available. My 1907 White Steamer has a feedwater heater, a part that bolts onto the cylinders. It’s made of aluminum, and over the 100-plus years it’s been in use, the metal has become so porous you can see steam and oil seeping through. I thought we could just weld it up. But it’s badly impregnated with oil and can’t be repaired. If we tried, the metal would just come apart.

So, rather than have a machinist try to copy the heater and then build it, we decided to redesign the original using our NextEngine 3D scanner and Dimension 3D printer. These incredible devices allow you to make the form you need to create almost any part. The scanner can measure about 50,000 points per second at a density of 160,000 dots per inch (dpi) to create a highly detailed digital model. The 3D printer makes an exact copy of a part in plastic, which we then send out to create a mold. Some machines can even make a replacement part in cobalt-chrome with the direct laser sintering process. Just feed a plastic wire—for a steel part you use metal wire—into the appropriate laser cutter.

Inside the printer, the print head goes back and forth, back and forth, putting on layer after layer of plastic to form a 3D part. If there are any irregularities in the originals, you can remove them using software. Once the model is finished, any excess support material between moving parts is dissolved in a water-based solution. Complexity doesn’t matter, but the size of the object does determine the length of the process. Making a little part might take 5 hours. The White’s feedwater heater required 33 hours.

Any antique car part can be reproduced with these machines—pieces of trim, elaborately etched and even scrolled door handles. If you have an original, you can copy it. Or you can design a replacement on the computer, and the 3D printer makes it for you.

People say, “Why not just give the part to your machinist to make?” Well, if the machinist makes it wrong, you still have to pay for it. The scanner allows you to make an exact copy in plastic, fit it and see that it’s correct. Even when you take plans to a machinist, it can be tricky. Say the part must be 3 mm thick here and 5 mm there. You get it back and then, “Oh no, it doesn’t fit; it’s too thick,” or “It’s too thin.” My setup lets you create the perfect part. And you could press the button again and again—and keep making the part—twice the size, half-size, whatever you need. If you have a part that’s worn away, or has lost a big chunk of metal, you can fill in that missing link on the computer. Then you make the part in plastic and have a machinist make a copy based on that example. Or you can do what we do—input that program into a Fadal CNC machine; it reads the dimensions and replicates an exact metal copy.

Some guys are so used to working in the traditional ways. They’re old-school. So they’ve never seen this new technology in use—in fact, they’re not even aware it exists. When you work on old cars, you tend to work with old machinery like lathes, milling machines or English wheels. When someone tells you that you can take a crescent wrench, for example, scan it, then press a button, copy it, and make a new wrench, these guys say, “Well, that’s not possible. You can’t make the little wheel that moves the claw in and out. You’d have to make it in two sections.”

But they’re wrong. You can duplicate the whole tool.

They stand in front of the machine and watch a wrench being made, and they still don’t believe it. It’s like The Jetsons. George Jetson would say, “I want a steak dinner.” He’d press a button and the meal would come out of the machine, with the roasted potatoes and everything, all on one plate. We may not have the instant steak dinner yet—but my NextEngine system is like the car-guy equivalent.

A 3D printer uses the data from the 3D scanner to build a plastic replica.

If you had a one-off Ferrari engine, you could scan each part and then re-create the entire motor. Right now, we’re scanning a Duesenberg body. It’s a classic example of high tech melding with old tech. There are cars sitting in garages around the country, and they haven’t moved in years for lack of some unobtainable part. Now they can hit the road once more, thanks to this technology.

My 1907 White engine would never have run again because its slide valve (or D-valve) was shot. We built that part, and now the car is back on the street.

Let’s say you have an older Cadillac or a Packard, and you can’t get one of those beautifully ornate door handles. You could go to the big swap meet in Hershey, Pa., every day for the rest of your life and never find it. Or you could take the one on the left side of your car, copy it, use the computer to reverse it, and put that new part on the other side.

It’s an amazingly versatile technology. My EcoJet supercar needed air-conditioning ducts. We used plastic parts we designed, right out of the 3D copier. We didn’t have to make these scoops out of aluminum—plastic is what they use in a real car. And the finished ones look like factory production pieces.

When I was in high school, a friend’s father bought the new Pulsar LED watch. He paid $2200 for it. It had a red face; you pressed a button, it lit up and gave you the time. The next year I bought a similar watch from Texas Instruments for $19.99. I went over and showed it to my friend’s dad, and he was sooo angry.

The NextEngine scanner costs $2995. The Dimension uPrint Personal 3D printer is now under $15,000. That’s not cheap. But this technology used to cost 10 times that amount. And I think the price will come down even more.

These machines are not suited for mass production, but they work well for rapid prototyping. Just as eBay has made many swap meets go away, this machine could eliminate the need to go to eBay for parts. Think about it: What old part do you want to make?

Late Night Hosts Love EVs, Part II: Jay Leno And The Aptera 2e

By Richard Read

Jay Leno and the Aptera 2e

Enlarge Photo

Not to be outdone by David Letterman's EV love-fest, Jay Leno has posted his review of the Aptera 2e to JayLenosGarage.com. Clearly, now is the time for all late night hosts to come to the aid of electric cars. Next up: Jon Stewart invites Sarah Vowell to help him take on the RORMaxx Formula AE. (We hope.)

In the clip, Leno and Aptera's low-key front man, Greg Wilbur, discuss the finer points of the 2e--notably, its look. Leno seems pretty well smitten on that front, saying that it's "an exciting looking automobile". Also exciting (at least for the folks at Aptera): someone with the star status and car cred of Jay Leno endorsing such an outside-the-box vehicle.

Of course, as funky looking as the 2e is, no review would be complete without putting it through its paces, and Leno does just that. Hurtling down the freeway, he praises its "George Jetson feel" and insists that it's fun to drive. The three-wheeled Aptera's only shortcoming? Dodging road hazards: "If you see a pothole in the road, you're gonna hit it with something."

There are two other great moments in the clip--the first being Leno's market analysis. He bemoans the high cost of EVs like the Tesla Roadster and says that "if they can bring [the Aptera 2e] in for under forty [thousand], I think it'll be, uh,...very, very exciting." It's the "uh" that kills us--as in, "it'll be, uh...very exciting...for the people who buy one, but I will not be in that number."

The second moment: when Leno half-jokingly encourages Aptera owners to save all the money they would've spent on gas and buy a private jet. Which would be possible, perhaps, but isn't part of the point of the 2e to cut down on air pollution--you know, like the air pollution caused by jet planes? Fifteen minutes in the air, and hell, you might as well buy a Hummer. (Assuming Hummer's still around, of course.)

Jay Leno books Conan O'Brien as last guest

O'Brien takes over 'Tonight Show' June 1

Associated Press

Jay Leno

Jay Leno's last guest on "Tonight Show" will be the man who's taking over for him -- Conan O'Brien.

Leno wraps up his 17-year-run as host of NBC's late-night show on May 29. The network says that O'Brien will be Leno's final guest. Then O'Brien steps in as "Tonight" host June 1.

The big names making the cut for Leno's final week of shows include Mel Gibson, Prince and Billy Crystal -- who was Leno's first guest when he took "Tonight" over from Johnny Carson in 1992.

Carson's final guests were Bette Midler and Robin Williams, who appeared on Carson's next-to-last show. He hosted his final "Tonight" broadcast without guests.

This fall, Leno will begin a daily prime-time show for NBC.

Jay Leno Predicts Future Collectable and Classic Cars

It's been 10 years since Jay Leno's garage first appeared in Popular Mechanics. But instead of looking back, Jay's celebrating his first decade with PM by looking forward--at which cars today have the potential to be collectible in the future.

Published in the May 2009 issue.

Stocks and bonds? I don’t know much about them. In fact, I don’t know anything about stocks and bonds. I’ve lost money in the stock market; come to think of it, I’ve lost money in real estate too. But I’ve never lost money on cars.

The reason is simple: I’ve always bought cars I really want to own. If you buy a car that you like, and it loses its value, at least you still like it. Besides, even if the car’s value does go down a little, it will come back up at some point down the road.

About 10 years ago, I had the chance to buy a McLaren F1. A new one was almost a million dollars. This was a secondhand car with less than 2500 miles, and it was $800,000. I thought, it’s crazy to spend that much money on a car. So I talked it over with my wife. And she said, “You’ve worked hard. If you want to get it, get it.” And I thought, ohhh ... kaaay! So I bought it.

Last year, a McLaren F1 sold at auction for $4.1 million! I now realize this is the greatest investment I’ve ever made. In less than 10 years, I more than quintupled my money. Best of all, I have a car I really enjoy. But there are plenty of modern cars you can buy at real-world prices that are fun to own.

People ask me if they should buy a new car and tuck it away as an investment. I think it’s ridiculous to buy something and just squirrel it away. The fuel will eventually go bad, all the moving parts will still have to be lubricated, and you still have to insure it. Cars should be driven. If you let a car sit, you’ll eventually have to flush the fuel system, replace the electronics and more. Buying any car and putting it into storage for years gets you nothing. It’s a bad idea. You won’t be buying something you like—you’re just trying to make money.

There are plenty of guys who bought the original Dodge Viper as an investment. When that car first came out in 1992, it produced 400 hp, an incredible level of power for that time. People thought, “That’s it. They’ll never make a car more powerful. I’ll buy one and stick it in my garage.” Now, every day people call me: “Hey, I’ve got a ’92 Viper with 800 miles.” Sorry, I’m not interested. “Three hundred miles?” Nope. You didn’t buy it to own it.

But there are some interesting modern cars that are potential collectibles you can drive and enjoy—cars considered common transportation today. I think the first-generation Toyota Prius is a future collectible. Although it was technically innovative at the time, now it just seems cute. It’s kind of slow, and it doesn’t have tremendous range. But it was the first of its kind—the first mass-produced hybrid—and there’s an honest simplicity to that. So if you have an original Prius, in 10 or 15 years, you’ll meet people who say, “I bought one of those!” And they’ll want to relive the feeling of watching the little dashboard display jump from charging to consuming. That neat feature will bring back a flood of those memories.

It’s like when I talk to people who once owned early and mid-1960s push-button Chryslers. They say, “I learned to drive in one of those! You press the D button to go, and you press R for reverse.” They remember that feeling of freedom and American progress—simply pressing buttons to drive down the road. So cars with unusual features, technology that cars today no longer have, can be collectible.

Years ago, I was told Mustangs would never be collectibles because Ford built millions of them. We’re a disposable society. But eventually, we want what we used to have—the cars we ran into the ground. We’ve used most of those old Mustangs up, and now they’re gone. So the survivors are highly prized.

Once, when I was visiting England, one of my relatives said, “You like motorcycles—you should talk to our vicar. He has one.” So I met the vicar, who owned a ’66 Honda 160. I asked how long he’d had it. He looked at me kind of quizzically and said, “I bought it new.” He’d had that bike his whole life, and he’d maintained it. To him it wasn’t a collectible. Many of us would say, “Oh, I had one of those, and my father threw it away,” or “We gave it to a neighbor,” or “We rode it to death,” or “We finally broke it and got something else.” In other countries, because motor vehicles aren’t seen so much as appliances, they’re treated with great respect. This vicar had been riding that Honda 160 for 40 years! It was his only transportation. And it was a survivor.

That’s the difference. We want what we used to have. We get rid of it, and then we pay 10 to 15 times over what it was worth originally just to get it back—often to recapture whatever lost youth we thought we had.

That’s why I think the Mazda Miata will be the ultimate affordable collectible by, say, 2025. The first-generation Miata was extremely simple, and that’s part of its charm. Years ago, when we were restoring Mustangs, they seemed so complicated compared to a Ford Model A.

A brake-light switch? Why do we have to have thaaaat? In a Model A, you just strung together a couple of yards of wire and boom! You were done. So the early Miata, with no traction control, no stability control—no nothing—will certainly be a collectible.

I think the first-generation Taurus, the forward-looking aerodynamic sedan, will be collectible too. That was seen as a real styling triumph in the mid-1980s. Almost anything built before today’s government safety regulations could be collectible. In the future, cars lacking these systems will appear so odd to people.

Obviously, Corvettes and Ford GTs will always be desirable, because they were collectibles from the day they came out. Back in the ’60s, who would have dreamed that a Corvette would have 638 hp and get 20 mpg? That was unheard of!

It’s harder to predict the ones you don’t necessarily remember off the top of your head—like the first-generation Honda Insight. Only about 18,000 were sold worldwide. But look at them now and you think, wow, it’s a two-seater, it gets up to 70 mpg, it’s got an interesting shape and it’s very aerodynamic. Any car that was ahead of its time, or any car that had an interesting flaw—that’s what collectors want.

Just as the much-maligned Ford Edsel of the late 1950s is collectible today, so too will be the Pontiac Aztek in the future. No kidding—Azteks will be really collectible if there are any of them left. The Aztek is so odd-looking and weird that people want to collect them, like the popular “nerd cars”—AMC Gremlins and Pacers and Ford Pintos. Remember those VW vans with all the windows, or even mid-1980s Chrysler K-cars with the fake wood? It looked fake then. It still looks fake. But today people want ’em. These models have personalities. They’re not jellybean cars.

Another one to watch will be the most recent version of the Cadillac CTS-V with a six-speed standard. In the future, the manual gearbox will almost become a curiosity. People who know how to shift one properly will be seen as skilled individuals who can really drive an old car. In 2025 they’ll say, “You can drive a 2009 556-hp Cadillac stick?” By then, everything will be some version of a double-clutch, automatic-synchro, paddle-shifter ... The fact that you might have one of those anachronisms, a Cadillac with a stick—that’ll seem unbelievable.

Despite all the abject scorn and hatred for the Hummer, it has to go on the collectible list. Hummers are languishing on used-car lots. The brand has become the poster boy for bad environmental behavior. But when we’re all driving hydrogen cars, someone will say, “Look at that thing. What the hell is that?” The Hummer will be the ’59 Cadillac of 2025. The Hummer went from being very desirable to just being hated. And I think the pendulum will eventually swing back the other way.

You know those Cadillac Escalades, with the big dub wheels and other flashy trim? When today’s young men are in their 50s and 60s, they’ll say, “I wanna drive one of those again and cruise around like we used to.” So, those ’Slades will be collectibles.

On the other hand, buying a modern Ferrari as a collector car is not a good idea. If you buy a ’50s to ’70s Ferrari, you could do the work yourself. But from the mid-1990s on, no one can do the work on it except Ferrari. For almost any other car, an onboard-diagnostic machine is $600 to $1000. For Ferrari, it’s something like $22,500. That’s what it costs. Just the handheld! So someone who does his own maintenance is simply not capable of repairing a late-model Ferrari—any profit you think you’ll make just isn’t going to happen.

One last collectible? It’s any car your girlfriend thinks is cute. A ’79 Ford Fiesta? “Oooh, look at that little thing!” It’s seen as a cute, desirable city car. The new Smart cars will always be collectible. Minis too. Things don’t change. If a woman was cute 20 years ago, she’s cute today. The same is true for cars.

NBC Expected to Give 10 P.M. Show to Leno

By BILL CARTER

Published: December 8, 2008

NBC will keep Jay Leno five nights a week, but in prime time, competing not with David Letterman, but with shows like “CSI: Miami.”

Paul Drinkwater/NBC, via Associated Press

Tonight show host Jay Leno gave his monologue in January.

The network will announce Tuesday that Mr. Leno’s new show will appear at 10 o’clock each weeknight in a format similar to “The Tonight Show,” which he has hosted since 1993.

Five years ago NBC announced that it would hand the job of host of that franchise show to Conan O’Brien in May 2009. Since then the network has maneuvered to try to keep Mr. Leno, who continues to be the late-night ratings leader, fearing that he could leave and start a new late-night show on a competitor’s network. “The Tonight Show” is seen at 11:35 weeknights.

Mr. Leno, 58, was known to have suitors, including ABC, the Fox network and the Sony television studio. But he was apparently persuaded to stay at NBC after aggressive personal wooing by Jeff Zucker, the chief executive of NBC Universal, a unit of General Electric.

Retaining Mr. Leno will undoubtedly be seen as a coup for Mr. Zucker, who has faced some serious questions about the wisdom of guaranteeing “The Tonight Show” to Mr. O’Brien and possibly losing Mr. Leno to another network.

Details of Mr. Leno’s agreement and the new show were provided by NBC executives who were briefed on the matter and who requested anonymity because they were not authorized to talk about the project until the network made its announcement.

The new show, which will begin next fall, is expected to be set in Mr. Leno’s longtime studio in Burbank, Calif. Mr. Leno is expected to retain many of the most popular elements of his “Tonight Show,” including his monologue and bits like “Headlines” and “Jay Walking.” One “Tonight Show” staff member said the new program would not be a variety show.

Mr. O’Brien, currently the host of NBC’s “Late Night,” will move “The Tonight Show” to a new studio on the NBC Universal lot in Universal City, Calif., in May. Mr. Leno, who is known to want to work as much as possible, would then miss only three months on the air, and would use that time to prepare his new show.

An executive involved in the discussions with Mr. Leno said that Mr. Leno finally came around to the idea that the television business had changed and a show like his could be a success in prime time.

Running the same show in prime time five nights a week would be a novelty for a broadcast network. Such so-called stripped shows have been a staple of daytime broadcasting.

The offer of a weeknight prime-time show is one that Mr. Zucker has favored for some time. In 2002, when David Letterman, Mr. Leno’s competitor at CBS, was contemplating whether to renew his contract, Mr. Zucker offered him a show at 8 o’clock weeknights. He turned it down.

Executives involved in the decision said Monday that because ratings have decreased and costs are becoming more critical, NBC could reap an enormous financial benefit from this move.

Though Mr. Leno will command an enormous salary, probably more than $30 million a year, the cost of his show will be a fraction of what a network pays for dramas at 10 p.m. Those average about $3 million an episode. That adds up to $15 million a week to fill the 10 p.m. hour. Mr. Leno’s show is expected to cost less than $2 million a week.

In addition, NBC will get more weeks of original programming. Network dramas typically make 22 to 24 episodes a year. Under this deal, the executives involved in the discussions said, Mr. Leno will perform 46 weeks a year.

That cost differential will probably be enough for NBC to absorb any fall in ratings from its current slate of dramas. Mr. Leno has averaged 4.8 million viewers for his show this year, with a rating of 1.3, or 1.7 million people, in the category of viewers ages 18 to 49, which most advertisers favor.

Few shows now at 10 p.m. could be considered hits. They include “CSI: Miami,” and “CSI: New York” on CBS and “Law & Order SVU” and “E.R.” on NBC. “E.R.” is about the leave the air. “SVU” will probably move to 9 p.m. next fall.

There have been no new hits at 10 p.m. on any network in almost four years; ratings for shows in that time slot continue to fall.

That does not mean that either the network or Mr. Leno has no risk in the move. Mr. Leno’s shows tend to fare best in their first half hour; if they were to decline too much in the second half hour, NBC’s affiliated stations would see their news shows adversely affected. And there may be some question about whether Mr. Leno’s show at 10 might diminish the stature of Mr. O’Brien’s “Tonight Show” at 11:35.

But Peter Lassally, the longtime late-night producer of shows starring Johnny Carson, Mr. Letterman and now Craig Ferguson, said that NBC came to Mr. Carson in the late 1980s with a similar idea, but that Mr. Carson turned it down.

“It’s all different now,” Mr. Lassally said. “The economic factors have changed so much it makes complete sense for NBC to try this.”

On Monday Mr. Zucker suggested at a news conference in New York that in the future networks might have to cut back the hours of prime-time programming. The program with Mr. Leno would effectively cut the number of hours NBC needed to fill each week from 22 to 17.

Mr. Leno had no comment. NBC executives also declined to comment. The network is expected to announce the deal with Mr. Leno in Los Angeles on Tuesday.
