NBC has put its Friday comedy block on hold. The network announced in May that it would premiere Community and Whitney on October 19 and air them in the Friday 8 PM hour. Now both shows’ return has been postponed, with Grimm reruns slated in the Friday 8 PM slot for the time being. The idea of launching a comedy block with younger-skewing comedies on the low-trafficked Friday night raised eyebrows in May. It was a decision made before the arrival of Jeff Bader as NBC’s new head of scheduling in August. In its statement today, NBC hints that Community and Whitney may be relocated to a higher-profile night Monday-Wednesday as replacements. So far, NBC has given new comedies Go On and The New Normal, which air on Tuesday, full-season orders. Guys With Kids and Animal Practice have struggled on Wednesday, though both posted week-to-week increases last Wednesday. Here is NBC’s statement:

Given the success we’ve had for the past four weeks – including winning the first week of the season in A18-49 – we’ve decided to continue to concentrate our promotional strength on our new NBC shows that are scheduled Monday through Wednesday and have therefore decided to hold COMMUNITY and WHITNEY from their previously announced premieres of October 19th.  Without having to launch these comedies on Friday at this time, we can keep our promotion focused on earlier in the week — plus we will have both comedies in our back pocket if we need to make any schedule changes on those nights.  When we have a better idea of viewing patterns in the next few weeks,  we will announce new season premieres of WHITNEY and COMMUNITY. “
