"Big Brother" returned last week to CBS with a special two-night premiere on Wednesday and Thursday.

The show's 26th season continues its Wednesday/Thursday/Sunday schedule this week but with new airtimes on weekdays, according to the network.

CBS announced last week the cast of 16 houseguests featured on Season 26, which features a crochet business owner and a former undercover cop, among others. The network also announced earlier this month the season's theme, which is "Big Brother Artificial Intelligence," or "BB AI."

“From summer camp, to tech, to the multiverse, 'Big Brother' loves to put a twist on topical and pop culture themes,” said executive producers Allison Grodner and Rich Meehan in a news release. “This summer’s ‘BB AI’ theme promises to bring the fun, the comedy and the unexpected game play that is a hallmark of 'Big Brother.'”
