CBS Shows 'Big Brother' And '3' Get Premiere Dates

CBS is revving up for a sizzling summer!

The network has announced that the season premiere of "Big Brother" will air on Thursday, July 12 at 9 p.m. ET.

The hit series, hosted by Julie Chen, follows a group of people living in isolation together who are constantly monitored by cameras as they struggle to avoid being evicted.

In addition to the show's return, fans have something else to get excited about: "Big Brother" will be broadcast on Wednesdays, Thursdays (the eviction episode) and Sundays, starting its second week. The first Sunday show of "Big Brother" will air on July 15 at 8 p.m. ET and the first Wednesday episode will air on July 18 at 9 p.m. ET. Then, it's back with its Thursday installment on July 19 at 9 p.m. ET.

The dating show "3" is also headed to CBS, which chronicles the lives of three very different single women who come together with the common goal of finding true love. "3" will kick off with a 90-minute premiere on Sunday, July 22 at 9 p.m. ET, with one hour episodes airing in the following weeks.
