Each year, a few familiar touchstones mark the passage of fall: trees shedding their leaves, the end of Daylight Saving Time and the ritual cancellation of broadcast's lowest-rated new shows. Yet for the first time in more than 15 years, the networks made it to November without pulling the plug on a single new series. Several freshman shows are rating a paltry 0.6 or 0.7 in adults 18-49, but instead of canceling them as usual, networks are keeping them on the air and reducing their 13-episode orders. Fox trimmed Minority Report's count to 10, while ABC did the same with Blood and Oil. NBC cut Truth Be Told's order to 10 and took The Player down to 9.
