'Online Nation' is canceled

Three episodes and out: "Online Nation," a YouTube-inspired clip show that premiered Sept. 30, has been canceled, a spokesman for the CW confirmed Thursday.

Instead, the CW will air encores of its new comedy, "Aliens in America," at 7:30 p.m. Sundays.

Since Fox still says that the previously shelved "Nashville" will be back later in the season, "Online Nation" is the first official casualty of the 2007-08 TV season.
