STEVE INSKEEP, HOST:

Good morning. I'm Steve Inskeep with condolences to ABC. For 263 weeks, ABC's "World News Tonight" trailed "NBC Nightly News." At last, they finally won a week.

In related news, this program remains far ahead of the competition with 17 trillion listeners. You're listening to MORNING EDITION. Transcript provided by NPR, Copyright NPR.
