|Big Brother Gameplay|
|Description||A display inside of the Big Brother House where all of the houseguests are displayed.|
|Appearance(s)||Big Brother 2 - onwards|
The Memory Wall is part of the Big Brother House. It consists of a section of wall containing photos of all the current contestants. When a HouseGuest is evicted, their picture changes from color to black and white.
- The Memory Wall pictures are actually small video monitors, allowing the seamless transition to black and white.
- Occasionally, the monitors will show different pictures as part of a competition.
- Three different Memory Walls have been used throughout the history of the show:
- The first, used from Big Brother 6 until Big Brother 13, had 2 rows of 5 screens under a third row with 4 screens.
- The second, used for Big Brother 14 and Big Brother 15, had 4 rows of 4 screens.
- The third and current, used from Big Brother 16 onwards, is composed of two large rectangular screens each segmented to display 8 houseguests' photos on them.
- The Memory Wall has occasionally caused issues in seasons where the number of houseguests doesn't match the number of spaces on the wall:
- Big Brother 9 had 16 houseguests competing. Since the Memory Wall only had 14 screens, the houseguests' photos were not put up until after the first 2 houseguests had been evicted. After Neil Garcia walked from the house and was replaced by Sharon Obermueller, her photo replaced his on the wall.
- Big Brother 10, Big Brother 11, and Big Brother 12 all only had 13 houseguests. In these seasons, the middle space on the Memory Wall displayed the Big Brother logo rather than a houseguest's photo.
- Big Brother 17 had 17 houseguests after Julia Nolan entered the game in week five, after initially starting with 16. When she entered, her photo replaced that of Jace Agolli, the first evictee in that season.
- Big Brother: Over The Top had only 13 houseguests, but continued using the same Memory Walll as Big Brother 18. The pictures were divided with 6 on one screen and 7 on the other, but in a slightly scattered look, compared to the organized look in the summer editions. In addition, there were still 16 key holes despite only 13 houseguests.
- Similarly to Big Brother 17, Big Brother 19 originally started with 16 houseguests, but after a temptation was taken, Paul Abrahamian was unleashed onto the house and he ended up taking the place of Cameron Heard, both in the game and on the Memory Wall, who ended up being the first evicted on Day 1.
- Though the screens change color live, they are not shown doing this action until the next episode; however, this happens occasionally.
- Since Big Brother Canada 2, the Canadian Memory Wall is giant full size portraits displayed the whole way around the backyard.
- Since Big Brother Canada 3, the Canadian Memory Wall shows their full bodies rather then just their heads.
- Coincidentally, from Big Brother 15 to Big Brother: Over The Top, the winner of the season has had their Memory Wall photo be on the farthest left side column.
- Jacob Heald and Cameron Heard are the only two houseguests to never have their faces be on the Memory Wall at any point since it's debut, due to the Memory Wall photos being put up after their evictions due to a large number of houseguests.
