( CNN ) -- NBC has canceled `` Whitney . '' And `` Guys With Kids . '' And `` Up All Night . '' And `` 1600 Penn . '' That 's four half-hour comedies axed in one afternoon . And those are in addition to `` 30 Rock '' and `` The Office , '' which are having their final seasons this year . And let 's not forget `` Animal Practice , '' the network 's previously cancelled comedy this season . And there still could be more carnage to come . We 're also awaiting word on the fates of freshman comedies Go On and The New Normal , along with perpetual underdog veteran `` Community . '' What has survived ? NBC renewed `` Parks & Recreation '' for a sixth season today . `` Parks '' is NBC 's best-performing show on Thursday night 's after The Office , though it has an average adults 18-49 rating that 's less than one third of CBS ' Thursday leader `` The Big Bang Theory '' ( 2.0 vs. 6.2 ) . NBC announced earlier that it will partly restock its lineup with a few new comedies . Highlights include Sean Hayes in Sean Saves the World , about a guy who must figure out how to parent his 14-year-old daughter , and a TV series version of the 2002 film `` About a Boy , '' starring David Walton as a bachelor whose primary goal in life is avoiding any kind of responsibility until he meets a geeky young boy . 'Community ' finale : The end ( for now ? ) But NBC will have a tough time regaining its former legendary Thursday night comedy dominance . CBS made serious inroads into the evening with `` Big Bang '' and `` Two and a Half Men '' frequently ruling the 8 p.m. hour . Recently CBS experimented with putting repeats of other comedies into the 9 p.m. hour , raising the possibility of a full-scale two-hour comedy invasion into the evening next fall . Expect more NBC and CBS prime-time moves over the next several days as broadcasters prepare for their upfront presentations in New York City next week . NBC will announce its new fall schedule on Sunday and CBS will unveil its plans on Wednesday . See the original article at EW.com .
