Keep in mind, at this point, this is no more than a rumor.
However, according to WrestlingInc.com:
Coming off the heels of the third and final hour of Monday's Raw broadcast suffering a fifteen percent drop in viewership, Comcast's listing for Monday night programming on the USA Network (available at TVGuide.com) has a rerun of NCIS: Los Angeles (2009 episode "Deliverance") airing during the 8:00 p.m. time slot with Raw listed as a two-hour-and-five-minute program beginning at 9:00 p.m.
Now, I am not one to write up a story without checking into it myself. So, I went to TVGuide.com, looked under TV listings, changed the date to Monday, Dec. 3 at 8:00 p.m. and scrolled down to the USA Network listing. To my surprise, Raw was indeed listed at 9:00 p.m., following a NCIS: Los Angeles rerun.
Still not 100 percent convinced, I went to my Verizon Fios guide, only to find a three-hour Raw still scheduled beginning at 8:00 PM. Ultimately, the 9:00 PM listing could be a glitch on TVGuide.com's website. On the other hand, they may be privy to some inside information and we could be hearing an official announcement by week's end.
As of this article, USA Networks website, still has the show slated for three hours. So, unless a press release comes from either USA or WWE, I would say this is a mistake on TV Guide's part.
Ultimately, I can't see the network making this kind of change before the New Year. Especially considering the TV business works in seasons. So, these types of moves typically happen when a new season begins, allowing the network time to promote it and giving viewers time to get used to the change.
The fact is, we are a little over a month away from the new TV season. So, to me, USA doesn't have anything to gain by making such a change before January. In the end, we will have to see how the rest of the week unfolds to find out if this is fact or just another Internet rumor.
