Fallon Will Start ‘Late Night’ on the Web

LOS ANGELES — With a new round of shake-ups in late-night television set to begin next year, Lorne Michaels has decided to try to get a jump on things by starting NBC’s next edition of “Late Night,” with its new host Jimmy Fallon, as a nightly entry on the Internet.

Mr. Fallon has been named as the replacement for Conan O’Brien when Mr. O’Brien takes over the “Tonight” show from Jay Leno next year, and Mr. Michaels, the long-time boss of NBC’s “Saturday Night Live,” who also serves as executive producer of “Late Night,” told television reporters here Sunday that he wants Mr. Fallon to work out as many of the rough spots in his presentation as possible in performances on a website.

Mr. Michaels said he did not know yet which site he will use to post the shows with Mr. Fallon, but he was sure of several of the plans:

The web performances will likely begin in the fall, long before the transition from Mr. Leno for Mr. O’Brien is set to take place. The entries will not constitute anything like an entire hour-long show. “I expect that we’ll do something like five or 10 minutes,” Mr. Michaels said.

But he said they most likely will be on every night, to try to establish the rhythm of a nightly show. And he said, “I’m going to post them at 12:30 every night, so people will begin to look for Jimmy at that time.”

NBC is expected to announce the schedule for the transition from Mr. Leno to Mr. O’Brien and from Mr. O’Brien to Mr. Fallon here tomorrow. NBC executives have previously said that Mr. O’Brien will probably stop production on his “Late Night” show in February, while he moves west and prepares to lead “Tonight” from a new stage now being built on the lot of the NBC Universal studio.

Mr. Leno is expected to continue until perhaps June. Mr. Michaels said Sunday that Mr. Fallon will definitely get some time on the air following Mr. Leno before Mr. O’Brien takes over “Tonight.” He pegged the likely start date for Mr. Fallon on the television version of the show as “sometime in the spring.”

One reason for trying out the show online, Mr. Michaels said, is that the Internet will allow Mr. Fallon more freedom in terms of what he can say and do, “more opportunity for experimentation,” Mr. Michaels said. But he added that he didn’t expect the show to push the line too far in terms of content. “I think we’re our own censors,” he said.

But the main reason for the idea, he said, was the experience of Mr. O’Brien, who endured a long period of uncertainty about whether he would survive after he assumed the desk on “Late Night” succeeding David Letterman. “Conan needed time to find his show,” Mr. Michaels said. “I think this will help Jimmy to do that.”
