The CW extended its order of Veronica Mars episodes this season to 20, short of the 22 typical of a full season, according to Josef Adalian of Variety:
CW only committed to 13 episodes of "Mars" last May when the net set its first-ever fall schedule. Its decision to add seven episodes to that order means the skein will live on -- but that prospects for a fourth season remain hazy if ratings don't pick up in the second half of the season.
Despite having a new and improved lead-in from ex-WB skein "Gilmore Girls," "Mars" has done little to improve its ratings this season, growing a scant 5% among the CW-friendly women 18-34 aud.
A fourth season of "Mars" is critical to producer Warner Bros. TV, since the studio needs to wrap a critical mass of episodes to ensure any sort of life for the show in syndication.
