Writers may have been enjoying a bit of shadenfreude today (Wednesday) after learning that CBS's decision to bring summer reality series Big Brother back into its lineup in February apeared to fail. Tuesday's first episode drew a lowly third-place 4.3 rating and a 6 share. Of course, it aired opposite a two-hour edition of American Idol that averaged a 17.3/25 overall and an 18.5/27 in the 9:00 p.m. hour opposite Brother.
