The Ticker: Demo Win, GMA Get, CNN Hi-Def…

> Countdown with Keith Olbermann beat The O’Reilly Factor in the 25-54 demo last Thursday. MSNBC tells us that has only happened once before: April 18, 2007. Bill O’Reilly was on vacation last week.

> Tomorrow on GMA, the father of former pro wrestler Chris Benoit sits down for his first in-depth interview. ABC says Michael Benoit will reveal new information in the murder case. The younger Benoit killed his wife and son, then killed himself.

> CNN has gone HD. The net launched CNN HD this week. For now, only select programs will be in high-def, including the NY-based shows American Morning, Lou Dobbs Tonight, Campbell Brown‘s soon-to-be launched 8pm show, and Anderson Cooper 360. CNN’s next two presidential debates (Nov. 15 & Nov. 28) will be in HD.
