Just put spoilers in title for further news
CBS announced that the 12th edition of Big Brother will premiere on Thursday, July 8. The network will air the reality show three nights a week on Wednesdays (8-9 p.m. ET/PT), Thursdays (eviction show from 8-9 p.m.) and Sundays (8-9 p.m).
CBS used to air BB on Tuesdays but the network wanted to keep its winning line-up of dramas on that night intact for the summer.
