Just a reminder that President Barack Obama is addressing the nation to night on the end of combat operations in Iraq. ABC, CBS, FOX and NBC all plan to carry the speech live at 8pm and the address is scheduled to be around 15 minutes.
ABC, CBS and FOX all just plan on pushing the existing schedules by ~15 minutes. So, look for Shaq Vs. Justin Bieber to begin around 9:15 instead of 9pm in the eastern and central time zones.
NBC plans to air an abbreviated version of Minute to Win It from ~8:20-9:00p with the regularly scheduled America's Got Talent starting on schedule at 9:00p.
Everything should run as normally scheduled in the mountain and pacific time zones.
