ABC announced today that it was picking up CASTLE for a complete season, in a move that was a no-brainer.  Sure, the show doesn’t stack up well in comparison to the complete ABC line up.  However, it does the best of any show in its time slot on the alphabet network.  Still there are many who look at TV BY THE NUMBERS excellent cancel/renew index that are asking why.

Profit.  CASTLE is starting to make some serious money for Disney.  That is what happens when you have a book based on the series hit number 1 in sales.  That’s right.  The cheesy tie in book written by the fake Richard Castle called HEAT WAVE about the Nikki Heat character based on the make believe Kate Becket character on the show has gone and sold a bazillion copies, staying on the NY Times Best Seller list for the past 4 weeks, and is currently the top selling book at Barnes & Noble, and the 8th best selling book at the time I checked on Amazon.

The DVD Sales have been above average for the ratings as well.

Not bad for a book written by an unknown writer.  Give the house of mouse some credit though.  They went all out in promoting the book written by a character on a TV show.  They totally made the incredibly weak GOD HATES US ALL book that Showtime pimped out to promote Season 3 of CALIFORNICATION look like child’s play.  They are totally treating the book as if Richard Castle was real.  It has worked.  All they had to do was give the real writer a couple guest spots as himself for a couple episodes as well.  Ego does wonders, eh?  (it also doesn’t hurt that the real writer is a good one).

Given the recent huge success of the book, it was a no brainer that ABC would give CASTLE a full season.  There is no better promotion for the series than a best seller.  Has it worked in viewers?  Some will argue it hasn’t, but the numbers state that the show has risen from a 2.2 to a 2.4 in the 18-49 category while the book has been on the NY Times Best Seller List.  A 2.4 for the time slot is a win for ABC.  If the show can grow to a 2.5+ they will have a solid show.  If it ever hits a 3.0+ then it’s a hit.

Disney currently has plans for a follow up book by Richard Castle as well.  So the future of this series may well live on past a second season despite what a certain index might show.
