ABC News

The [itvt] editorial team is on the road this week and next, so we are covering most stories in round-up/summary form, and we anticipate that there will be some additional interruptions of our regular news publishing schedule beyond that. We apologize in advance for any inconvenience to our readers.

In a posting on its Web site, Monday, ABC News announced that its long-running nightly news magazine show, "Nightline," is expanding its relationship with microblogging service, Twitter, to launch a new, weekly, half-hour broadband TV show that will be hosted by "Nightline's" regular anchors and correspondents, and that it says will provide a forum for viewers to use Twitter to simultaneously discuss and debate the news of the day.
