On the demand side, this lifecasting stuff would never have caught on if there wasn't an audience for what it produces. And there is, as we can tell from television's Big Brother. I can understand why people want to watch that show when participants are screaming abuse at one another or making fools of themselves in public. But there are plenty of people who watch it when everyone in the Big Brother house is asleep.

In effect, anyone who wants to wear a camera (and carry around a laptop with a wireless card) could be a star in this new genre. There was a rumour going around that actress Natalie Portman was in Silicon Valley looking for financing for a "lifecasting" project, one that would give people a glimpse behind the scenes. The actress's representatives denied the rumour.

Justin Kan has strapped a camera to the side of his head, and he won't turn it off.

For over a week, Kan has been video blogging nonstop, 24/7. Everything he does (including going to the bathroom) streams live on http://www.Justin.tv, where his phone number is posted for fans to call him and a chat room facilitates discussion.

He calls it "lifecasting."
