CANCELLATION ALERT: CSI: Miami, Rob, Unforgettable, NYC 22

CBS is the last network to make moves and today they did ahead of Upfronts this week as CSI: Miami, Rob, Unforgettable, and NYC 22 joined How to Be a Gentleman and A Gifted Man on CBS's cancellation pile.

The biggest surprise (but it has been rumored for weeks) was the cancellation of CSI: Miami after ten seasons and 232 episodes. The first spinoff from CSI was a Monday night staple for many many years but in Fall 2010, it moved to Sundays at 10pm where it has aired the last two years. The show outperformed CSI: NY but it was on a night with more pressure and is reportedly more expensive to make. Still, the show is a huge success in syndication and worldwide and will probably continue to be in repeats for years to come. All shows must end sometime and CBS made the call to end one of its long running dramas. It's too bad that fans didn't get a proper series finale however.

Also cancelled was freshman comedy Rob. The show performed decently airing after The Big Bang Theory from January-March but retention was very poor. It's quite likely that this show would have gotten a renewal if CBS was moving to four hours of comedy but this cancellation and the fact that they only picked up two sitcoms seems to suggest that they will not be doing so.

Two freshman dramas were also cancelled - Unforgettable aired a full season on Tuesday nights but never did too much in the demo as it couldn't top previous occupant The Good Wife in the demo and dropped as the season went on. Though it was billed as TV's top new drama at the beginning of the season, Person of Interest soon eclipsed it on the network alone and the show had very little buzz. NYC 22 was a late entry on Sunday nights and seemed to be an afterthought from CBS. Not surprisingly, it tanked as there always seems to be one drama that CBS throws on at the end of the season that bombs (Chaos and Miami Medical in the previous two years).
