I also noticed there were no autumn backgrounds for the satellite LF's. The exception was at 7:08AM ET and 8:08AM ET, during AMHQ; Those two LF's had the autumn scenes.
This screams apathy on the part of TWC. These LF backgrounds are obviously in their library and would have cost them ZERO to implement. For all the noise regarding cut backs of celebrity talent (Al Roker) to save money, simply using the change of seasons to add to the flavor of the programming seems to be a no brainer.
But - - having been a loyal viewer since the 1980's, I see the trend. TWC will spend a heap of cash to bring in celebrities but will ignore the simple and free (no licensing required) things to make their channel more of a pleasure to watch.
