Diane's Baby Bump

Diane Sawyer's debut as anchor of ABC's "World News" appears to have boosted viewership of the evening newscast, even during a slow holiday week. According to early Nielsen data, an average of 8.9 million people tuned in to ABC from 6:30 to 7 p.m. Monday night. That's only a rough indication of the true viewership of "World News," because not every station carries the broadcast during that time period. But it's larger than the newscast's season-to-date average of 8 million viewers and this season's Monday average of 8.4 million viewers.

By comparison, 9.3 million viewers tuned in to NBC during the time period and 5.9 million people watched CBS. Final Nielsen data will be available next week.  Wash Post
