In any other TV universe, shows with viewership levels so low you can count them on your fingers and toes would have been canceled by now. But since the WGA remains on strike, the Big Four networks are being surprisingly kind to their so-called bubble shows (i.e. freshman series that have yet to receive orders for the back nine episodes). Says one suit, “With a strike going on it’s not fatal to leave them. So you tap dance with mediocrity. You don’t want to reach into your reserves more quickly than you have to because you know you’ll need stuff down the road.” So if you’re wondering why struggling series like CBS’ Cane (9 million) and Fox’s K-Ville (5.4 million) haven’t been officially yanked, now you know. Other bubble shows include ABC’s Big Shots (8.8 million), Carpoolers (7 million), and Cavemen (6.6 million), and NBC’s Bionic Woman (9.9 million) and Journeyman (7.2 million).
