Tomorrow (November 7th), the Disney/ABC Television Group will launch a new feature on ABC.com, that will allow users to view complete episodes of selected programs, and then create their own “commentary tracks” using their Facebook account.

The pilot episode of ABC’s new sci-fi series “V” will launch the ABC Social: Episode Commentary service, with commentaries by executive producers Scott Peters and Steve Pearlman.

From the press release:

To create and share their own fan commentary tracks, participants can go to ABC.com and log on using their Facebook account. As they view an episode in Commentary Mode, they can simultaneously add their own comments and read expert commentary, as well as see comments from their Facebook friends. Actions taken on ABC.com will be shared in the viewer’s Facebook stream, alerting friends to view the episode online and add their own comments…

Expert commentary featured in the Full Episode Player will vary from episode to episode and may include insights from a series’ producers, writers and directors, stars of the series, production and costume designers, music supervisors and network executives, among others.

The Hollywood Reporter points out that other networks, like ABC Family and NBC, have experimented with adding social networking capabilities to their online video content. But ABC appears to be the first to align its offering with a powerhouse site like Facebook, which has 300 million active users and Alexa ranking of 2.

ABC is experimenting with inserting advertising in the comment stream.
