and thus even though most would rather the black list be back behind the voice since its slot is hurting its ratings power . nbc has decided after revealing it did a purge of shows like about a boy and constatine the prime after voice slot that has wound up making shows for the network hits . even when the voice is not on . that nbc has come fall given the slot to  bloodsport which is about a a woman played by jamie alexander with no memory and an fbi agent tatooed on her . and also the rebirth of heroes will be on thurs with the blacklist which stays put and thus nbc risking both it continuing to lose its power and the voice  track record of any show following it becoming a hit with a new one bloodsport. plus putting the rebirth of heros the same night as the black list. taking risk for fall. with two of its big players the voice and black list.
