 Celebrating at the “X” camp was somewhat dampened when NBC announced plans to run three hours of “The Voice” in “X’s” space during the week of the Presidential elections (“The Voice” will be pre-empted from its usual Tuesday timeslot that week because that’s election night).

How rude of NBC, given how nice Fox was to change plans to repeat last week’s botched “X” episode on Tuesday.

 Meanwhile, Showtime has announced it had ordered a 12-episode third season of Emmy-sweeping “Homeland” the morning after the second episode of Season 2 scored 1.75 million viewers – the biggest audience to date for any of its episode’s premiere telecasts.

 And, CW announced it had ordered a full season on  “Arrow” —  maybe the most success new-series launch of this season to date.

 The drama, based on DC Comic’s Green Arrrow, opened with more than 4 million viewers tuned in — CW’s biggest crowd in three years. In its second broadcast, “Arrow” held on to all of its young-adult audience — a first for a drama launch so far this season.
