The Big Brother House is reopening. CBS has confirmed that Big Brother has been renewed for a 27th season, which will air this summer, starting on Thursday, July 10th.

A reality competition series, the Big Brother TV show is hosted by Julie Chen Moonves and typically airs three nights a week — Wednesdays (veto), Thursdays (eviction), and Sundays. The 26th season cast includes a celebrity chef, a former undercover cop, an event bartender, a former marine, a physical therapist, and a crochet business owner. The show follows a group of people living together in a house outfitted with 94 HD cameras and 113 microphones, recording their every move 24 hours a day. Each week, one or more people are voted out of the house. In the end, only one will be awarded the grand prize of $750,000.

Here are the details about season 27:
