Twitter, the Web site that asks what everybody's doing, says it wants to be doing a TV series.

The social-networking service has teamed with Reveille productions and Brillstein Entertainment to develop an unscripted series based on the site, which invites brief, 140-character postings from members all over the world.

The show would harness Twitter to put players on the trail of celebrities in a competitive format.

The producers call their planned series the first to bring the immediacy of Twitter to the TV screen.

But they're offering no further details on the interactive show's format or when it might hit the air.
