"To celebrate 10 seasons of BIG BROTHER we are going 'old school' and returning to the original concept for the show - A group of strangers living together in a house and battling it out for half a million dollars. All 13 Houseguests have no prior relationship - they are not exes, nor secret couples," said executive producer Allison Grodner. "We are also excited to have the most diverse group we have ever assembled. They range in age from 22 to 75, come from all walks of life, and have distinct points of view. This should make for an unforgettable BIG BROTHER summer."

BIG BROTHER 10 will debut Sunday, July 13 (8:00-9:00 PM, ET/PT) on the CBS Television Network. Following the premiere, BIG BROTHER 10 will be broadcast three nights weekly, on Sundays (8:00-9:00 PM, ET/PT), Tuesdays (9:00-10:00 PM, ET/PT) and the live eviction show, hosted by Julie Chen, Wednesdays (8:00-9:00 PM, live ET/delayed PT).

BIG BROTHER follows a group of people living together in a house outfitted with dozens of cameras and microphones recording their every move 24 hours a day. One by one, the Houseguests will vote each other out of the house. At the end of three months, the last remaining Houseguest will receive the Grand Prize of $500,000.

This season, Houseguests will move into a brand new, all-American home with a traditional look, with a rocking chair on the front porch, Victorian stenciled windows and a lush flower garden. Like the contestants who will inhabit it, each room has a different style and flair, including a groovy "Road to Woodstock" bedroom, a rad '80s "Punk Room" and a classic retro 1950s style kitchen. Additionally, the house comes equipped with a Jacuzzi and swimming pool in the backyard.
