What time does 'Big Brother' air Sunday? Episode to start much later
"Big Brother" is scheduled to air late Sunday, from 10:30-11:30 p.m. ET following the conclusion of "The Summit." However, NFL football airs on CBS from 1-7:30 p.m. If the games run late, the network's evening programming could be delayed. In that case, "Big Brother" would air after the conclusion of "The Summit."
