The CW is pulling the plug on its latest attempt to launch scripted comedies. Online-to-TV transplant Backpackers and Canadian import Seed are coming off the schedule immediately. Next Monday, the CW’s lineup was already pre-empted for the Young Hollywood Awards. For the two following Mondays, the network will air Arrow repeats behind an original and encore of Whose Line Is It Anyway? On August 18, the 21st cycle premiere of America’s Next Top Model will air in the hour, where the veteran reality series will spend six weeks before moving to its regular Friday 9 PM time slot. (Its lead-in will be Whose Line original and repeat on August 18 and magic series Masters Of Illusion and Whose Line rerun starting the following Monday.) Top Model originally was slated to return on August 22 it its Friday 9 PM berth. It now will be double-pumped for the first six weeks, with repeats airing on Fridays.
