From wolfenm at Joseph Mallozzi's blog:
So I saw a commercial during Sanctuary that was all about Rodney; it was cool, but confused me at first, because it said "new episode" at the bottom of the screen, yet was showing old clips. Then they finally got to the point: that the time slot has been changed.
ATTN ALL: ATLANTIS HAS BEEN MOVED TO 9 PM EST!!
Not 10 PM. Still on Fridays, at least.
I do hope Skiffy starts pointing this out more, because only ONE of the other commercials I've seen made any special note of the new time slot. Otherwise, the new time is listed, sure, but unless you're thinking about it, it's not "Oh! The time has changed!" Ya know? I hope the people who are avoiding Skiffy's spoilerrific commercials and who don't frequent this blog's comments section still find out about the time change.
"First Contact" will air before the new episode, "The Lost Tribe", and Sanctuary will air immediately after.
New Stargate Atlantis episodes will air at 9pm (EST)/8pm (CST) on Fridays.
The previous week's episode will air at 8pm (EST)/7pm (CST) on Fridays.
Sanctuary will air at 10pm (EST)/9pm (CST).
