For the first time since 2008, ABC's World News has beaten NBC's Nightly News in the demo.
BriWi and the gang at NBC has won 25-54 year old demo since November 2008. ABC passed NBC by almost 40,000 viewers in the Key Demo.
Nightly News kept it's streak alive by pulling in more total viewers, but the Demo streak is no more.
It ABC can pull out another demo victory this week, look for full on panic to set in at 30 Rock.
