In the past I have noticed that The CW airs some of its programs before 8pm. I found this a bit odd but since I dont watch The CW very often it wasnt a big deal. Now I see that other stations are doing the same practice. Fox is airing "Til Death" at 7pm and CBS is airing "Without A Trace" at 7pm tonight. Why the sudden change? Is this just a rare occurance for these stations because of NFL Playoff games? Or are these changes that we should expect for the future? Just curious.
