With CBS being as strongly of a performing network that it is, most of its long running series will be returning for Fall. However, there were still a few casualities of both freshman and long-running series.
Here are the CBS series that have been chopped:
Worst Week - The freshman comedy about a guy that couldn't catch a break with his fiance's parents could not catch a break itself. The series was given a prime slot in CBS's Monday night comedy lineup and did not manage to break out as a new hit. 15 episodes aired.
Eleventh Hour - Also a freshman series starring Rufus Sewell, Eleventh Hour focused on a special science adviser to the US government that solved crimes of a paranormal nature (ummm, Fringe for CBS, perhaps?). According to Wikipedia, the series averaged over 12 million viewers for the season, which is by no means a flop, but with breakouts like The Mentalist, the network decided they could do better for Fall. 18 episodes aired.
The Unit - Sunday night companion to Cold Case, it was rumored for awhile that this series would not survive. Averaging 9 to 11 million viewers, it was CBS's second lowest performing drama and perpetually on the bubble. 4 seasons aired.
Harper's Island - This limited edition crime mystery was designed to exist as a single, 13 episode run. However, if the series broke out as a hit, the creator explained that additional cycles could be run with a new cast (since mostly everyone is dying) and a new mystery. Alas, it did not break out. The remainder of the 13 episode order is airing on Saturday nights.
Without a Trace - Perhaps the most perplexing of all of the CBS cancellations, Trace - about an FBI unit that searched for missing persons - performed admirably for the network for 7 years! In fact, in its heyday, the show grabbed almost 19 million viewers on Thursday nights and trounced NBC's ER. Since moving out of that slot, numbers have decreased, though the show was still the 16th best performing show of the season (according to Nielsen). However, it was determined that the aging show had become too expensive to produce. 7 seasons aired.
