At its upfront in May, the CW announced that The Carrie Diaries will succeed departing Gossip Girl in the Monday 9 PM slot in midseason, Deadline said.

Now the network has tweaked its plans, setting the Sex And The City prequel series for a January 14 premiere at 8 PM.

The newbie will swap slots with veteran 90210, which will slide to 9 PM. The rationale behind the decision is that, like fall breakout Arrow, Carrie Diaries will be supported by a big marketing push, which may make it a better 8 PM anchor just like Arrow is on Wednesdays, lifting veteran Supernatural with it. A sneak peak from The Carrie Diaries will be featured during the December 17 two-hour series finale of Gossip Girl.

The CW will formally announce the rest of its midseason schedule at a later date, but the majority of its lineup is expected to return to originals the week of January 14.

Based on the novels by Candace Bushnell, Carrie Diaries is set in the 1980s and chronicles the teen years of Carrie Bradshaw (AnnaSophia Robb). Warner Bros TV and CBS TV Studios produce in association with Fake Empire, with executive producers Josh Schwartz, Stephanie Savage, Len Goldstein, writer Amy B. Harris and Bushnell.
