ABC has been running promos for World News Tonight featuring Charles Gibson during Good Morning America, Nightline, and other programs. The ads advertise Gibson as “Your Trusted Source.”

“He’s been there. Seen it. Brought us the world,” the narrator says. It shows Gibson interviewing Bush and Clinton and reporting from New Orleans, among other locales. “In times like these, it’s impotrant to trust the source,” the ad says.

The new tag line, “Your Trusted Source,” sounds a lot like “Trust is Earned,” a 2005 ad campaign for Peter Jennings, an e-mailer notes.

> Also: The promo says “Charles Gibson” is joining WNT. An e-mailer asks: “Didn’t they always call him Charlie on GMA?”
