With the premiere of season 23 right around the corner, Big Brother has been around for just over two decades. The first season premiered in April 2001 and ran for 12 weeks until the live finale. The competition series was an immediate success and has aired at least one season every year since then.

Throughout the years, houseguests from all over have come in and out of the infamous house, with just a handful leaving half a million dollars richer. While longtime viewers think they know almost everything there is to know about both the show and the competition itself, only super fans will know these behind-the-scenes facts.

Many fans know houseguests are not allowed to sing inside the house due to copyright laws. They do receive music during their HOH reign, which they can only listen to with headphones. However, every morning, the houseguests are awoken by loud music playing throughout the house.

Cameras Are Everywhere, Even the Bathroom

There are over 100 cameras inside the Big Brother house, capturing every moment all summer long. While many would assume the houseguests can only find privacy while in the bathroom, that is actually not entirely true. The bathrooms do have cameras inside them as well. However, they are rarely ever used. This is to prevent houseguests from gathering in the small room to have secret conversations.

Getting Expelled Is Possible

There are a lot of rules houseguests must follow after arriving inside the Big Brother house. If a contestant chooses to disregard these rules, they can possibly be expelled from the show. A few of the show's most controversial players have been expelled.

It's Not A 'Real' House

Although the Big Brother home looks like an actual house, houseguests are really living inside a sound stage created to look like a house. Past contestants have explained it does not feel like they are living inside of a house due to the high ceilings and bright lights. This is why many contestants are oftentimes seen wearing sunglasses inside the house.

'Wall Yellers'

Almost every summer, production must deal with the issue of "wall yellers." These are fans that go to the studio lot where the Big Brother house is located and yell things to the players from the other side of the wall. By doing this, fans are attempting to give the players information regarding the game or the outside world, which could interfere with the competition.
