Tom Green has been toiling for the last six months on a late-night talk show – the sort of thing he once did for MTV.

However, unless you’ve been in front of a computer visiting tomgreen.com, you probably don’t know about it.

“We’re in the grassroots phase,” Green said. “This has been a real cool experience. I have this set in my living room, we come up with ideas in the afternoon and execute it, basically, immediately.”

Green said the show, which runs weeknights at 11 (episodes remain on the site indefinitely) is modeled after classic talk shows such as Tom Snyder’s “Tomorrow” and Jack Paar’s “Tonight Show.”

He’s got guests – they’ve ranged from Brooke Shields to Dr. Drew Pinsky – and he takes calls from viewers.

“The exciting thing about the Internet is people can watch it anywhere in the world,” Green said. “The potential is unlimited. Granted, more people were watching my MTV show than there are watching this show in this current moment in time. But I really do believe the Internet and television are converging.”

And Green is positioning himself for the future.

He started out doing his own show for public-access television in Canada in the early 1990s. By 2000, he had a talk show on MTV, and he has since appeared in several movies.

Outside of work, there was his highly publicized, and brief, marriage to Drew Barrymore and his battle with testicular cancer – which he documented for television.

At the beginning, there weren’t a lot of people watching “Tom Green Live,” he said. Cameras occasionally wouldn’t work, and the computer streaming the show would conk out. Now, with technical issues resolved, he estimates there could be 50,000 people watching live.

The show is on hiatus for the holidays and will return with a live edition on Jan. 8.

So far there are no advertisers, but Green said he expects backing in the new year. And he’s talking about syndication down the road.

On the Internet, he has total control over the content – something he appreciates, having worked for TV networks. He doesn’t miss the network world, where jokes are watered down before they hit the airwaves.

“By the time a joke got approved, it almost wasn’t even funny,” Green said. “I was like, “I don’t even want to do it.”‘

But just because he can push the envelope these days, that doesn’t mean he’s doing it.

“I’ve made the choice, with my show, to not go with the “Hey, we can do anything’ model,” he said. “We’re floating in a sea of smut. You can see anything you want on the Internet. We’re reveling in the ability of making the TV show we want to make and keep it spontaneous, and not have to prove it to anyone before we put it on the air.”
