The most recent episode of "Nation" earned a 0.2 rating among adults 18 to 49. That number matched its lead-in, magazine show "CW Now." But "Now" was pre-sold under a unique commercial-free sponsorship arrangement with Mediavest that has helped protect the show.
"Aliens" got off to a rough start in The CW's Monday night comedy block, but this week showed some ratings growth in key demos.
Networks have been cautious this season about canceling shows due to the possibility of a writers strike. Fox has also pulled a show from its schedule -- the docu-soap reality series "Nashville" -- but the network says the series may return in November, especially if there's a strike.
The CW was the first network this season to pickup a full season of a freshman series when it ordered the back nine episodes of "Gossip Girl."
UPDATE: "Online Nation" hosts respond to cancellation ("Are you sure they said 'cancellation' and not 'celebration'?").
